Overview

Trulia is redefining the home search experience for consumers and changing the way that real estate professionals build
their businesses. Our marketplace, delivered through the web and mobile applications, gives consumers powerful tools to research homes and neighborhoods and enables real estate professionals to efficiently market their listings and attract new
clients. We believe we deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer free and subscription products
that provide real estate professionals with access to transaction-ready consumers and help them enhance their online presence. In the year ended December 31, 2012, we had 23.1 million monthly unique visitors. As of December 31, 2012,
we had more than 390,000 active real estate professionals in our marketplace, 24,443 of whom were paying subscribers.

We
empower consumers to make more informed housing decisions by delivering the inside scoop on homes, neighborhoods, and real estate professionals through an intuitive and engaging user experience. Our large, continually refreshed, and
searchable database contains more than 112 million properties, including 4.1 million homes for sale and rent. We supplement listings data with local information on schools, crime, and neighborhood amenities to provide unique insights into
each community. In addition, we harness rich, insightful user-generated content from our active community of contributors, which includes consumers, local enthusiasts, and real estate professionals. With more than 7 million unique user
contributions, we believe we have the largest collection of user-generated content on homes, neighborhoods, and real estate professionals.

We enable real estate professionals to better promote themselves and their listings and connect with transaction-ready consumers through our online and mobile marketing products. Our free products allow
real estate professionals to build their personal brand by creating an online profile, contributing content to our marketplace, leveraging social media for endorsements, and establishing their presence through mobile features such as
check-ins. Our subscription products enable real estate professionals to increase their visibility, promote their listings in search results, target mobile users, and generate more highly qualified leads from our large audience of
transaction-ready consumers. We believe that our audience is highly motivated and ready to purchase homes, as supported by our surveys conducted between January 2012 and December 2012 in which 76% of over 543,000 respondents contacting real estate
professionals through our marketplace indicated that they are planning to move in the next six months, and almost half of over 382,000 respondents stated that they are pre-approved for a mortgage. We believe that the combination of our compelling
solution with our transaction-ready audience results in a high return on investment for real estate professionals who purchase our subscription products.

We benefit from powerful network effects and a vibrant user community. Consumers contribute content by posting questions, reviewing neighborhoods, and writing agent recommendations. Real estate
professionals, seeking to connect with our consumers, engage in our community by sharing local knowledge, answering consumers questions, and contributing content to our marketplace. The breadth and quality of user-generated content contributed
to our marketplace has helped to build our brand, deepen the engagement of our existing users, and attract more users.

We are a leading mobile platform for the home search process and mobile devices are
increasingly critical to consumers and real estate professionals. We have introduced iPhone, iPad, Android Phone, Android Tablet, Kindle, and Windows 8 applications that provide tailored mobile experiences, which has led to rapid growth in mobile
use of our solution. In the year ended December 31, 2012, we had over 5 million mobile monthly unique visitors, an increase of 144% over 2011. In addition, our mobile users are more likely than our web users to contact real estate
professionals through our marketplace.

Our online marketplace is experiencing rapid growth. Monthly unique visitors to our
marketplace increased to 23.1 million in the year ended December 31, 2012 from 7.9 million in the year ended December 31, 2010, or a 192% increase, and our subscribers increased to 24,443 as of December 31, 2012 from
10,070 as of December 31, 2010, or a 143% increase. We generate revenue primarily from sales of subscription products to real estate professionals. We also generate revenue from display advertising sold to leading real estate and consumer brand
advertisers seeking to reach our attractive audience. For the years ended December 31, 2010, 2011, and 2012, we generated revenue of $19.8 million, $38.5 million, and $68.1 million, respectively. During the same period, we had net losses of
$3.8 million, $6.2 million, and $10.9 million, respectively.

Industry and Challenges

The residential real estate industry, which we estimate accounts for more than a trillion dollars in annual spending in the United States,
is undergoing a profound transformation. Technology is changing the way that consumers search for homes and the way in which real estate professionals attract clients and build their businesses. In addition, as the U.S. housing market recovers from
its recent unprecedented downturn, real estate professionals are seeking more effective ways to market themselves and achieve a greater return on their marketing investment. These trends present significant opportunities to capitalize on shifts in
behavior.

Historically, consumers lacked readily available access to detailed and comprehensive information essential to
making housing decisions, relying instead on disparate sources of information such as real estate professionals, local newspapers, and word of mouth. Over time, more information has become available online and, as a result, the Internet has become a
primary source of research for housing decisions. According to a November 2012 survey by the National Association of Realtors, a trade organization for real estate professionals, 90% of home buyers used the Internet to research homes. Additionally,
the use of mobile devices for home searches has become more prevalent. According to a 2012 survey by The Real Estate Book, a real estate website, 52% of respondents reported using a mobile device to look for homes, with 85% of non-users stating that
they would consider using a mobile device for their next search.

As consumers increasingly research homes online, real estate
professionals are shifting their marketing expenditures online to reach prospective clients. While initially these real estate professionals focused their spending on email, search, and creating websites with listings, now these professionals are
increasingly using online real estate marketplaces to generate leads.

With technology driving the home search process online,
consumers, real estate professionals, and advertisers face distinct challenges. Consumers are challenged to effectively compile and use fragmented information, gain local insights, and obtain information on the go.Real estate professionals
are challenged to reach todays online consumers, target the right leads, manage their businesses while on the go, and optimize their marketing spend. Advertisers are challenged to efficiently reach the right consumers while maximizing the
effectiveness of their advertising.

Market Opportunity

We believe that there are significant opportunities to address the challenges faced by consumers, real estate professionals, and advertisers. Borrell Associates, Inc., an advertising research and
consulting firm, estimated in

an August 2012 industry paper that $23.7 billion would be spent in 2012 on real estate-related marketing in the United States. According to a November 2012 survey by the National Association of
Realtors, 90% of home buyers used the Internet to research homes. However, according to the Borrell Associates report, only 55% of the real estate marketing dollars in the United States were projected to be spent online in 2012. We believe that
there is a disconnect between where marketing dollars are spent and where consumers research homes. Therefore, we expect that real estate-related marketing spend will continue to migrate online from traditional channels.

Large, continually refreshed, searchable database of homes for sale and rent. We provide consumers with access to a large, continually
refreshed, and searchable database of properties. We enable consumers to customize their searches with property-specific filters to obtain up-to-date listings that are rich with property facts, price, and sale data.



Trusted insights, social recommendations, and proprietary analytics that provide local context. We provide consumers with local insights,
critical to a successful home search, not available elsewhere on an easy to use and comprehensive basis. These insights include information about schools, crime, neighborhood amenities, and real estate professionals.



Anytime and anywhere access. Our marketplace is accessible anytime and anywhere on the web and on major mobile platforms. Since the introduction
of our first mobile application in 2008, mobile use of our marketplace has grown rapidly.

Key
benefits for real estate professionals



Broad reach to transaction-ready consumers. We provide real estate professionals the ability to connect with our large audience of
transaction-ready consumers at scale on the web and through our mobile applications. We believe that a large portion of consumers using Trulia do not use other real estate websites, and that this enables real estate professionals on Trulia to
effectively identify and market themselves to consumers that they cannot find anywhere else.



Products that boost presence and deliver high-quality leads. Our free products enable real estate professionals to create and manage an online
profile, promote their personal brand with consumers by contributing content to our marketplace, and leverage social media for endorsements. Our subscription products enable real estate professionals to boost their visibility, promote their listings
in search results, and generate more high-quality leads from potential home buyers.



Anytime and anywhere access to critical information and tools. We offer mobile applications designed specifically for real estate professionals
to take their business on the go. Using our mobile applications, real estate professionals can access critical information that they need to conduct their business, including listings details, contacts, driving directions, and local information
about neighborhoods.



Significant return on investment. We believe that our subscription products deliver a high return on investment to real estate professionals.

Key benefits for advertisers



Attractive audience. We believe our audience is highly attractive to consumer brand advertisers. A substantial portion of our audience is either
college educated, has a household income above $75,000,

or is in the 25 to 54 age group. U.S. consumers with these characteristics tend to spend more of their annual income on home maintenance, insurance, household furnishings, apparel and
services, and entertainment than the average consumer, according to the Bureau of Labor Statistics 2011 Consumer Expenditure Survey, which makes our audience attractive for consumer brand advertisers.



Display advertising products that efficiently reach target consumers. We enable our advertisers to reach segments of our audience that are
attractive to them. Advertisers benefit from improved reach, impact, relevancy, and measurement of their marketing campaigns in our marketplace.

Our Strengths

We believe that our competitive advantage reflects the
following strengths:



We deliver the inside scoop. We are one of the leading online real estate marketplaces and provide consumers with powerful tools and
unique content that together deliver valuable insights into homes, neighborhoods, and real estate professionals. For example, our crime heat maps provide consumers with a view into neighborhood safety and our Facebook integration gives consumers
recommendations on real estate professionals from people in their social network. Through our Trulia Voices forum, we also provide consumers with local content from our community of contributors, including consumers, local enthusiasts, and
real estate professionals.



Superior products and user experience. We believe we have the best products in the industry for consumers and real estate professionals. We
invest significant resources into technology development and product design to create a superior user interface that provides compelling features and rich functionality for our users.



Large, differentiated, transaction-ready audience. Our website and mobile applications have attracted 23.1 million monthly unique visitors
in the year ended December 31, 2012 and, based on data from comScore, Inc., a marketing research company, a significant portion of our visitors do not visit our primary competitors websites. For instance, according to comScore, during
each month in 2012 and 2011, more than 54% and 64%, respectively, of our audience did not visit Zillow.com. We believe that our audience is highly motivated and ready to purchase homes, as supported by our surveys conducted between January 2012 and
December 2012 in which 76% of over 543,000 respondents contacting real estate professionals through our marketplace are planning to move in the next six months, and almost half of over 382,000 respondents stated that they are pre-approved for a
mortgage.



Strong mobile monetization. We believe that we are one of the few companies that is monetizing its mobile products at a higher rate than web
products. Since we launched our subscription product for mobile devices in May 2012, we have sold this product at prices that yield a higher average monthly revenue per subscriber than our subscription products that are not focused on mobile
devices. In addition, our users are more likely to contact real estate professionals through our mobile applications than our website.



High ROI for real estate professionals. We believe our subscription products provide compelling value and a better return on investment than
other marketing channels. On average during the year ended December 31, 2012, paying subscribers received more than 13 times the number of monthly leads compared to real estate professionals who only used our free products.



Powerful network effects driven by unique content. We benefit from a self-reinforcing network effect that helps build our brand, drives user
engagement in our marketplace, and attracts more users to our website and mobile applications. Consumers post questions in our marketplace, attracting real estate professionals who add more content by answering these questions, which in turn
attracts more consumers to our marketplace.



Big data and analytics platform. We employ proprietary advanced analytics and heuristics capabilities to aggregate, filter, and analyze large
amounts of data from disparate sources that we have cultivated

over the years. Our expertise in handling large amounts of externally-sourced data and combining it with user activity data collected from our marketplace allows us to improve the user experience
by developing innovative new tools and new functionality.

Our Strategy

Our goal is to build the leading online real estate marketplace. We intend to focus on the following key strategies in pursuit of our
goal:



Expand our audience and increase user engagement. We intend to grow our large, transaction-ready audience by continuing to offer superior
products for consumers. We plan to continuously enhance and refresh our database of homes, partner with third parties to add new and relevant local content, and encourage our users to contribute useful content. We also plan to develop new features
and tools that deepen our users engagement with our website and mobile applications, and to promote and foster interaction in our vibrant user community.



Grow the number of real estate professionals in our marketplace. We intend to further penetrate the large base of more than 2.8 million
real estate professionals in the United States by communicating the value proposition of our free and subscription products, growing our audience of transaction-ready consumers, and creating additional products.



Increase revenue. We plan to increase our revenue by selling more subscription and advertising products and by optimizing our pricing.



Increase brand awareness. We have built a leading real estate and consumer brand with limited marketing spend to date. We plan to continue to
grow our brand by providing our users with superior and innovative products.



Pursue strategic opportunities. We plan to pursue acquisitions of complementary businesses and strategic partnerships to help us execute on and
accelerate our growth plans.



Pursue adjacent opportunities. We plan to pursue opportunities in a number of large adjacent markets, such as rentals, mortgages, home
improvement, and agent tools, and to expand our business internationally.

We count a unique visitor the first time a computer or mobile device with a unique IP address accesses
our website or our mobile applications during a calendar month. If an individual accesses our website or mobile applications using different IP addresses within a given month, the first access by each such IP address is counted as a separate unique
visitor. We calculate our monthly unique visitors based on the monthly average over the applicable period. Our number of monthly unique visitors includes mobile monthly unique visitors.

For an explanation of our key business metrics, see the section titled Managements Discussion and Analysis of Financial
Condition and Results of OperationsOverviewKey Business Metrics.

Non-GAAP Financial Measures

Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles in the United
States, or GAAP. We define Adjusted EBITDA as net loss adjusted to exclude interest income, interest expense, taxes, depreciation and amortization, change in the fair value of our warrant liability and stock-based compensation. Below, we have
provided a reconciliation of Adjusted EBITDA

to our net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any
other measure of financial performance calculated and presented in accordance with GAAP. Our Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate Adjusted EBITDA in
the same manner as we calculate the measure.

We include Adjusted EBITDA in this prospectus because it is an important measure
upon which our management assesses our operating performance. We use Adjusted EBITDA as a key performance measure because we believe it facilitates operating performance comparisons from period to period by excluding potential differences primarily
caused by variations in capital structures, tax positions, the impact of depreciation and amortization expense on our fixed assets, changes related to the fair value remeasurements of our preferred stock warrant, and the impact of stock-based
compensation expense. Because Adjusted EBITDA facilitates internal comparisons of our historical operating performance on a more consistent basis, we also use Adjusted EBITDA for business planning purposes, to incentivize and compensate our
management personnel, and in evaluating acquisition opportunities. In addition, we believe Adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our
industry as a measure of financial performance and debt-service capabilities.

Our use of Adjusted EBITDA has limitations as
an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:



Adjusted EBITDA does not reflect our cash expenditures for capital equipment or other contractual commitments;



Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and
Adjusted EBITDA does not reflect capital expenditure requirements for such replacements;

Adjusted EBITDA does not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our
indebtedness; and



Other companies, including companies in our industry, may calculate Adjusted EBITDA measures differently, which reduces their usefulness as a
comparative measure.

In evaluating Adjusted EBITDA, you should be aware that in the future we will incur
expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating
our performance, you should consider Adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described
below, together with all of the other information in this prospectus, before making a decision to invest in our common stock. If any of the risks actually occur, our business, financial condition, operating results, and prospects could be materially
and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment.

We have a limited operating history in an evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk that we will not be successful.

We have a limited operating history in an evolving industry that may not develop as expected. Assessing our business and future prospects
is challenging in light of the risks and difficulties we may encounter. These risks and difficulties include our ability to:



increase the number of consumers using our website and mobile applications;



continue to obtain home listing information, as well as information on schools, crime, and neighborhood amenities;



increase the number of real estate professionals subscribing to our products;

successfully compete with other companies that are currently in, or may in the future enter, the business of providing residential real estate
information online and on mobile applications, as well as with companies that provide this information offline;



successfully compete with existing and future providers of other forms of offline, online, and mobile advertising;



successfully navigate fluctuations in the real estate market;



effectively manage the growth of our business;



successfully expand our business into adjacent markets, such as rentals, mortgages, and home improvement;



successfully integrate companies we may acquire; and



successfully expand internationally.

If the demand for residential real estate information online does not develop as we expect, or if we fail to address the needs of consumers, real estate professionals, or advertisers, our business will be
harmed. We may not be able to successfully address these risks and difficulties, which could harm our business and cause our operating results to suffer.

We have a history of losses and we may not achieve or maintain profitability in the future.

We have not been profitable on a quarterly or annual basis since we were founded, and as of December 31, 2012, we had an accumulated deficit of $47.1 million. We expect to make significant future
investments in the development and expansion of our business which may not result in increased revenue or growth. In addition, as a public company, we have incurred and expect that we will continue to incur significant legal, accounting, and other
expenses that we did not incur as a private company. As a result of these increased expenditures, we must generate and sustain increased revenue to achieve and maintain future profitability. While our revenue has grown in recent

periods, this growth may not be sustainable and we may not achieve sufficient revenue to achieve or maintain profitability. We may incur significant losses in the future for a number of reasons,
including slowing demand for our products, increasing competition, weakness in the residential real estate market, as well as other risks described in this prospectus, and we may encounter unforeseen expenses, difficulties, complications and delays,
and other unknown factors. Accordingly, we may not be able to achieve or maintain profitability and we may continue to incur significant losses in the future, and this could cause the price of our common stock to decline.

If real estate professionals do not continue to subscribe to our products, or we are unable to attract new subscribers, our business and operating
results would be harmed.

We rely on subscriptions purchased by real estate professionals to generate a substantial
portion of our revenue. Subscriptions accounted for 47%, 58%, and 67% of our revenue in 2010, 2011, and 2012, respectively. We generally offer subscriptions for periods between one month to 12 months, with most real estate professionals preferring
to subscribe for periods shorter than 12 months.

Our ability to attract and retain real estate professionals as subscribers,
and to generate subscription revenue, depends on a number of factors, including:

A key focus of our sales and marketing activities has been to further penetrate the large base of more than 2.8 million real estate professionals in the United States. As of December 31, 2012,
we had more than 390,000 active real estate professionals in our marketplace and 24,443 total subscribers. We spend a considerable portion of our operating expenses on sales and marketing activities. Our sales and marketing expenses were our largest
operating expenses in the years ended December 31, 2011 and 2012. Sales and marketing expenses reflect many of the costs that we incur in acquiring new subscribers and retaining existing subscribers, and we expect that sales and marketing
expenses will continue to increase in absolute dollars as we seek to grow the number of subscribers in our marketplace. If we are unable to increase the number of total subscribers in our marketplace, our revenue may not grow and our operating
results could suffer.

Real estate professionals may not continue to subscribe with us if we do not deliver a strong return on
their investment in subscriptions, and we may not be able to replace them with new subscribers. In addition, real estate professionals sometimes do not renew their subscriptions with us because of dissatisfaction with our service. This may occur for
a number of reasons, including because we have made changes to our products or services, which we do periodically. If subscribers do not renew their subscriptions with us with the same or higher subscription fees, or at all, or if we are unable to
attract new subscribers, our business and operating results would be harmed.

Further, although a majority of our revenue in
the years ended December 31, 2011 and 2012 was generated from subscriptions purchased by real estate professionals, we cannot be certain that subscribers will renew their subscriptions with us and that we will be able to achieve the same or
higher amounts of subscription revenue in the future.

Our ability to increase the number of subscribers to our services also
depends, to some degree, on whether we can increase the inventory of marketing products and services available for us to sell in different geographic markets. If we are unable to create additional inventory by offering new services or reconfiguring
our existing services, we may not be able to grow the number of subscribers to our services quickly or at all.

In addition, if we need to reduce our subscription fees due to competition, our business,
operating results, financial condition, and prospects would suffer if we are unable to offset any reductions in our fees by increasing our number of consumers and advertisers, reducing our costs, or successfully developing and deploying new features
on a timely basis.

If we are not able to optimize our pricing and increase our average revenue per subscriber, we may not be able to
grow our revenue over time.

Our ability to grow revenue depends, in part, on our ability to optimize pricing and
increase average monthly revenue per subscriber over time. Since launching our first subscription product in 2007, we have continued to expand our products and optimize pricing of our products. In the year ended December 31, 2012, our average
monthly revenue per subscriber was $156 compared to $110 in the year ended December 31, 2011. As we continue to optimize our pricing, real estate professionals may not accept these new prices, which may harm our business and growth prospects.

If advertisers reduce or end their advertising spending with us, or if we are unable to attract new advertisers, our business and
operating results would be harmed.

Display advertising accounted for 53%, 42%, and 33% of our revenue in 2010, 2011,
and 2012, respectively. Our advertisers can generally terminate their contracts with us at any time or on very short notice. Our ability to attract and retain advertisers, and to generate advertising revenue, depends on a number of factors,
including:



the number of consumers using our website and mobile applications;



our ability to continue to attract an audience that advertisers find attractive;

how advertisers value our advertising network, which consists of our online properties and those of our publishing partners;



the amount of spending on online advertising generally; and



our ability to deliver an attractive return on investment to advertisers.

We may not succeed in capturing more spending from advertisers if we are unable to demonstrate to advertisers the effectiveness of
advertising in our marketplace as compared to alternatives, including traditional offline advertising media such as newspapers and magazines.

If advertisers reduce or terminate their advertising spending with us and we are unable to attract new advertisers, our revenue, business, operating results, and financial condition would be harmed. For
example, although we experienced sequential increases in media revenue during each of the eight quarters ended December 31, 2011, media revenue growth slowed during the years ended December 31, 2011 and 2012. In our display advertising
business, we also have a limited ability to replace the loss of revenue resulting from the loss of a customer during a particular quarter because of the significant time required to secure an alternative advertiser for such advertising inventory,
run the alternative advertising campaign on our marketplace, and satisfy our revenue recognition criteria from such campaign. As a result, the loss of a customer during a quarter could result in our inability to replace the lost revenue from such
customer within that quarter and, therefore, we will sometimes encounter variances in our media revenue.

If we cannot obtain
comprehensive and accurate real estate listing information, our business will suffer.

Our offerings are based on
receiving current and accurate real estate listing data. We depend on, and expect to continue to depend on, relationships with various third parties to provide this data to us, including real estate listing aggregators, multiple listing services,
real estate brokerages, apartment management companies, and other

third parties. Many of our agreements with our listing sources are short-term agreements that may be terminated with limited or no notice. If our relationship with one or more of these parties is
disrupted, the quality of the experience we provide to users would suffer.

We currently depend on a listing aggregator to
provide us with a substantial portion of the unique listings in our database. While these listings are available from their original sources, it would take substantial time and effort for us to aggregate these listings from all of the original
sources. Therefore, if the agreement with our largest listing aggregator is terminated, we may not be able to fully replace the listings in a timely manner or on terms favorable to us, or at all, which would adversely affect our business and
operating results. In addition, as real estate brokers typically control the distribution and use of their listings, our business could suffer if real estate brokers withheld their listings from us. From time to time in the past, real estate brokers
have refused to syndicate their listings to us, and we cannot assure you this will not happen in the future. If real estate brokers refuse to syndicate listings to us, the quality of our products would suffer due to the decline of timely and
accurate information, which could adversely affect our business and operating results.

If use of our mobile products does not continue
to grow or we are not able to successfully monetize them as we expect, our operating results could be harmed and our growth could be negatively affected.

Our future success depends in part on the continued growth in the use of our mobile products by our users and our ability to monetize them. During the year ended December 31, 2012, our mobile
products accounted for 22% of our total traffic compared to 14% of our total traffic for the year ended December 31, 2011. We currently monetize our mobile offerings through our Trulia Mobile Ads subscription product for real estate
professionals, through our mobile website, m.trulia.com, and through certain of our mobile applications. We monetize our mobile products principally through our Trulia Mobile Ads subscription product through which real estate
professionals can purchase local advertising on our mobile applications and our mobile website by zip code and by share of a given market. We monetize our mobile website through the sale of display advertisements and we also provide our subscribers
rotational placement in a local lead form that appears on certain pages of our mobile website. We also sell display advertising on certain of our iPhone and iPad applications and expect to offer display advertising on our other mobile applications
in the future. The use of mobile technology may not continue to grow at historical rates, and consumers may not continue to use mobile technology for real estate research. Further, mobile technology may not be accepted as a viable long-term platform
for a number of reasons, including actual or perceived lack of security of information and possible disruptions of service or connectivity. In addition, traffic on our mobile applications may not continue to grow if we do not continue to innovate
and introduce enhanced products on mobile platforms, or if users believe that our competitors offer superior mobile products. The growth of traffic on our mobile products may also slow or decline if our mobile applications are no longer compatible
with operating systems such as iOS, Android, Windows 8, or the devices they support. Additionally, real estate professionals and advertisers may choose to devote less of their spending to target mobile users for a number of reasons, including a
perceived lack of effectiveness of display advertising on mobile devices. Although we have seen strong results in our mobile product monetization efforts with the launch of Trulia Mobile Ads in May 2012, we cannot assure you that we will
continue to monetize our mobile products as effectively in the future. If use of our mobile products does not continue to grow, or if real estate professionals or advertisers decrease their spending on our mobile products, our business and operating
results could be harmed.

If we do not continue to innovate and provide useful products, we may not remain competitive, and our
business and financial performance could suffer.

Our success depends in part on our ability to continue to innovate.
This is particularly true with respect to mobile applications, which are increasingly being used by our audience. Our competitors regularly enhance their offerings and create new offerings for consumers, real estate professionals, and others
involved in the residential real estate industry. If we are unable to continue to offer innovative products or to keep pace with our competitors offerings, our business and operating results will suffer.

We rely on Internet search engines to drive traffic to our website, and if we fail to appear high up
in the search results, our traffic would decline and our business would be adversely affected.

We depend in part on
Internet search engines, such as Google, Bing, and Yahoo!, to drive traffic to our website. For example, when a user types a physical address into a search engine, we rely on a high organic search ranking of our webpages in these search results to
refer the user to our website. However, our ability to maintain high organic search result rankings is not within our control. Our competitors search engine optimization, or SEO, efforts may result in their websites receiving a higher search
result page ranking than ours, or Internet search engines could revise their methodologies in a way that would adversely affect our search result rankings. If Internet search engines modify their search algorithms in ways that are detrimental to us,
or if our competitors SEO efforts are more successful than ours, overall growth in our user base could slow. Search engine providers could provide listings and other real estate information directly in search results or choose to align with
our competitors. Our website has experienced fluctuations in search result rankings in the past, and we anticipate similar fluctuations in the future. Any reduction in the number of users directed to our website through search engines could harm our
business and operating results.

Our recent revenue growth rates may not be indicative of our future growth, and we may not continue to
grow at our recent pace, or at all.

From 2008 to 2012, our revenue grew from $8.1 million to $68.1 million, which
represents a compounded annual growth rate of approximately 70%. In the future, our revenue may not grow as rapidly as it has over the past several years. We believe that our future revenue growth will depend, among other factors, on our ability to:

attract a growing number of users to our website and mobile applications;



increase our brand awareness;



successfully develop and deploy new products for the residential real estate industry;



maximize our sales personnels productivity;



respond effectively to competitive threats;



successfully expand our business into adjacent markets, such as rentals, mortgages, and home improvement; and



successfully expand internationally.

We may not be successful in our efforts to do any of the foregoing, and any failure to be successful in these matters could materially and adversely affect our revenue growth. You should not consider our
past revenue growth to be indicative of our future growth.

Our revenue and operating results could vary significantly from period to
period, which could cause the market price of our common stock to decline.

We generate revenue through sales of
subscriptions to real estate professionals and sales of display advertising to advertisers. Our subscription and advertising sales can be difficult to predict and may result in fluctuations in our revenue from period to period. Our revenue and
operating results have fluctuated in the past, and may continue to fluctuate in the future, as a result of a variety of factors, many of which are outside of our control. As a result, comparing our revenue and operating results on a period-to-period
basis may not be meaningful, and you should not rely on past results as an indication of future performance.

Our revenue,
operating results, or both, may be affected by a number of factors, including:

fluctuations in user activity on our website and mobile applications, including as a result of seasonal variations;



competition and the impact of offerings and pricing policies of our competitors;



the effects of changes in search engine placement and prominence of our website;



the amount and timing of operating expenses related to the maintenance and expansion of our business, operations, and infrastructure;



our ability to control costs, particularly those of third-party data providers;



our ability to reduce costs in a given period to compensate for unexpected shortfalls in revenue;



the timing of costs related to the development or acquisition of technologies or businesses;



our inability to complete or integrate efficiently any acquisitions that we may undertake;



our ability to collect amounts owed to us from advertisers;



changes in our tax rates or exposure to additional tax liabilities;



claims of intellectual property infringement against us and any resulting temporary or permanent injunction prohibiting us from selling our products or
requirements to pay damages or expenses associated with any of those claims;



our ability to successfully expand in existing markets and enter new markets;



our ability to keep pace with changes in technology;



changes in government regulation affecting our business;



the effectiveness of our internal controls;



conditions in the real estate market; and



general economic conditions.

For example, individuals hired to join our sales team typically do not reach their maximum productivity until they have been employed for several months or more. Our fixed expenses related to the addition
of personnel may not result in an increase in revenue in a given period or at all.

As a result of the foregoing factors and
others discussed in this Risk Factors section, our operating results in one or more future periods may fail to meet or exceed our projections or the expectations of securities analysts or investors. In that event, the trading price of
our common stock would likely decline.

From time to time, we experience seasonality in subscription revenue and display advertising due to fluctuations in
traffic to our website and mobile applications. During the fourth quarter of each year, traffic to our marketplace has historically declined and our revenue has historically grown more slowly than in other quarters or has declined sequentially.
Conversely, we typically experience higher growth in traffic and revenue during the spring and summer months, when consumers are more likely to buy new homes. We expect that seasonality will continue to affect traffic in our marketplace, as well as
our revenue from subscriptions and advertising.

Our business and financial performance are affected by the health of, and changes
to, the residential real estate industry. Although we have built and grown our business during a worldwide economic downturn, home-buying patterns are sensitive to economic conditions and tend to decline or grow more slowly during these

periods. A decrease in home purchases could lead to reductions in user traffic, reductions in subscriptions by real estate professionals, and a decline in marketing spend. Furthermore, online
advertising products may be viewed by some existing and potential advertisers on our website and mobile applications as a lower priority, which could cause advertisers to reduce the amounts they spend on advertising, terminate their use of our
products, or default on their payment obligations to us. In addition, we may become subject to rules and regulations in the real estate industry that may restrict or complicate our ability to deliver our products. These changes would harm our
business and operating results.

Most recently, beginning in 2008, domestic and global economic conditions deteriorated
rapidly, resulting in a dramatic slowdown in the housing market, which slowed advertising spending in the real estate industry. In addition, changes to the regulation of the real estate industry and related areas, including mortgage lending and the
deductibility of home mortgage interest, may negatively affect the prevalence of home purchases. Real estate markets also may be negatively impacted by a significant natural disaster, such as earthquake, fire, flood, or other disruption. Declines or
disruptions in the real estate market or increases in mortgage interest rates could reduce demand for our products and could harm our business and operating results.

We participate in a highly competitive market, and pressure from existing and new companies may adversely affect our business and operating results.

The market to provide home listings and marketing services for the residential real estate industry is highly competitive and fragmented.
Homes are not typically marketed exclusively through any single channel. Consumers can access home listings and related data through more than one source. Accordingly, current and potential competitors could aggregate a set of listings similar to
ours. We compete with online real estate marketplaces, such as Zillow.com and Realtor.com, other real estate websites, and traditional offline media. We compete to attract consumers primarily on the basis of the number and quality of listings; user
experience; the breadth, depth, and relevance of insights and other content on homes, neighborhoods, and professionals; brand and reputation; and the quality of mobile products. We compete to attract real estate professionals primarily on the basis
of the quality of the website and mobile products, the size and attractiveness of the consumer audience, the quality and measurability of the leads we generate, the perceived return on investment we deliver, and the effectiveness of marketing and
workflow tools. We also compete for advertisers against other media, including print media, television and radio, social networks, search engines, other websites, and email marketing. We compete primarily on the basis of the size and attractiveness
of the audience; pricing; and the ability to target desired audiences.

Many of our existing and potential competitors have
substantial competitive advantages, such as:



greater scale;



stronger brands and greater name recognition;



longer operating histories;



more financial, research and development, sales and marketing, and other resources;



more extensive relationships with participants in the residential real estate industry, such as brokers, agents, and advertisers;

The success of our competitors could result in fewer users visiting our website and mobile applications, the loss of subscribers and advertisers, price reductions for our subscriptions and display
advertising, weaker operating results, and loss of market share. Our competitors also may be able to provide users with products that are different from or superior to those we can provide, or to provide users with a broader range of products and
prices.

We expect increased competition if our market continues to expand. In addition, current or
potential competitors may be acquired by third parties with greater resources than ours, which would further strengthen these current or potential competitors and enable them to compete more vigorously or broadly with us. If we are not able to
compete effectively, our business and operating results will be materially and adversely affected.

If our users do not continue to
contribute content or their contributions are not valuable to other users, our marketplace would be less attractive, which could negatively affect our unique visitor traffic and revenue.

Our success depends on our ability to provide consumers with the information they seek, which in turn depends in part on the content
contributed by our users. We believe that one of our primary competitive advantages is the quality and quantity of the user-generated content in our marketplace, and that information is one of the main reasons consumers use our platform. If we are
unable to provide consumers with the information they seek because our users do not contribute content, or because the content that they contribute is not helpful and reliable, the number of consumers visiting our website and using our mobile
applications may decline. If we experience a decline in consumers visiting our website and using our mobile applications, real estate professionals and advertisers may not view our marketplace as attractive for their marketing expenditures, and may
reduce their spending with us. Any decline in visits to our website and usage of our mobile applications by consumers and any decline in spending by real estate professionals and advertisers with us would harm our business and operating results.

In addition, we monitor new contributions to user-generated content because we believe this metric is a key indicator of our
user engagement and the strength of our community. In the event that the number of new contributions to user-generated content declines, this metric may provide a leading indicator of the health of our business. However, if the quantity of new
contributions to user-generated content continues to increase but the quality of user-generated content declines, this metric would not capture any corresponding declines in user engagement or the strength of our community as evidenced by the lower
quality of user-generated content, and such data would be of limited use in those circumstances.

Our growth depends in part on our
relationship with third parties to provide us with local information.

Third parties provide us with information that
we use to provide users with insights that go beyond listings, such as information about schools, crime, and neighborhood amenities. Property descriptions and sale transactions obtained via third-party data providers also inform the valuations
provided by our Trulia Estimates feature. If these third-party data providers terminate their relationships with us, the information that we provide to users may be limited or the quality of the information may suffer. If we are unable to
renew our agreements with these data providers on favorable terms to us or to secure alternative sources for this information, our costs may increase and our business may be harmed.

If we do not display accurate and complete information on a timely basis, our user traffic may decline, our reputation would suffer, and our business and operating results would be harmed.

We receive listing and other information provided by listing aggregators and other third parties that we include on
our website and mobile applications. Our reputation with consumers depends on the accuracy and completeness of the information that we provide, although the accuracy and completeness of this data is often outside of our control. We cannot
independently verify the accuracy or completeness of all of the information provided to us by third parties. If third parties provide us with inaccurate or incomplete information that we then display on our website and mobile applications, consumers
may become dissatisfied with our products, our traffic may decrease, and our reputation may suffer. Real estate professionals also expect listings data and other information to be accurate and complete, and to the extent our information is incorrect
or incomplete, our reputation and business relationships may suffer.

In addition, we update the listing information that we
provide on our website and mobile applications on a daily basis. To the extent that we are no longer able to update information in our marketplace on a timely basis,

or if consumers begin to expect updates in a more timely manner, we may be forced to make investments which allow us to update information with higher frequency. There can be no assurance that we
will be able to provide information at a pace necessary to satisfy consumers in a cost-effective manner, or at all.

Growth of our
business will depend on a strong brand, and any failure to maintain, protect, and enhance our brand would hurt our ability to retain or expand our base of users, or our ability to increase their level of engagement.

We believe that a strong brand is necessary to continue to attract and retain consumers and, in turn, the real estate professionals and
others who choose to advertise on our websites and mobile applications. We need to maintain, protect, and enhance the Trulia brand in order to expand our base of users and increase their engagement with our website and mobile
applications. This will depend largely on our ability to continue to provide high-value, differentiated products, and we may not be able to do so effectively. While we may choose to engage in a broader marketing campaign to further promote our
brand, this effort may not be successful. Furthermore, negative publicity about our company, including our content, technology, sales practices, personnel, or customer service could diminish confidence in and the use of our products, which could
harm our operating results. If we are unable to maintain or enhance user and advertiser awareness of our brand cost effectively, our business, operating results, and financial condition could be harmed. In addition, our website serves as a forum for
expression by our users, and if some of our users contribute inappropriate content and offend other users, our reputation could be harmed.

We rely on a small number of advertising partners for a substantial portion of our media revenue, and we are subject to risks as a result of this
advertiser concentration.

In the years ended December 31, 2010, 2011, and 2012, the ten largest advertising
partners accounted for 50%, 50%, and 63% of our media revenue, respectively. One of our growth strategies is to increase the amount large advertisers spend in our marketplace, and we expect this revenue concentration to continue. If one or more of
these large advertisers were to decrease or discontinue advertising with us, our business and operating results will be adversely affected.

Our operating results may be adversely affected by a failure to collect amounts owed to us by advertisers.

We often run display advertisements in our marketplace prior to receiving payment from an advertiser, which makes us subject to credit
risks. In the past, certain advertisers have been unable to pay us due to bankruptcy or other reasons, and we cannot assure you that we will not experience collection issues in the future. If we have difficulty collecting amounts owed to us by
advertisers, or fail to collect these amounts at all, our results of operations and financial condition would be adversely affected.

We
depend on our talented personnel to grow and operate our business, and if we are unable to hire, retain, manage, and motivate our personnel, or if our new personnel do not perform as we anticipate, we may not be able to grow effectively.

Our future success will depend upon our continued ability to identify, hire, develop, motivate, and retain talented
personnel. We may not be able to retain the services of any of our employees or other members of senior management in the future. We do not have employment agreements other than offer letters with any key employee, and we do not maintain key person
life insurance for any employee. In addition, from time to time, there may be changes in our senior management team that may be disruptive to our business. If our senior management team fails to work together effectively and to execute our plans and
strategies, our business could be harmed.

Our growth strategy also depends on our ability to expand our organization by
hiring high-quality personnel. Identifying, recruiting, training, integrating, managing, and motivating talented individuals will require significant time, expense, and attention. Competition for talent is intense, particularly in the San Francisco
Bay Area, where our headquarters is located. If we are not able to effectively recruit and retain our talent, our business and our ability to achieve our strategic objectives would be harmed.

Growth may place significant demands on our management and our infrastructure.

We have experienced substantial growth in our business that has placed, and may continue to place, significant demands on our management
and our operational and financial infrastructure. As our operations grow in size, scope, and complexity, we will need to improve and upgrade our systems and infrastructure. The expansion of our systems and infrastructure will require us to commit
substantial financial, operational, and technical resources in advance of an increase in the volume of business, with no assurance that the volume of business will increase. Continued growth could also strain our ability to maintain reliable service
levels for our users and advertisers, develop and improve our operational, financial, and management controls, enhance our reporting systems and procedures, and recruit, train, and retain highly skilled personnel.

Our products are accessed by a large number of users, often at the same time. If the use of our marketplace continues to expand, we may
not be able to scale our technology to accommodate increased capacity requirements, which may result in interruptions or delays in service. The failure of our systems and operations to meet our capacity requirements could result in interruptions or
delays in service or impede our ability to scale our operations.

Managing our growth will require significant expenditures
and allocation of valuable management resources. If we fail to achieve the necessary level of efficiency in our organization as it grows, our business, operating results, and financial condition would be harmed.

Our success will depend, in part, on our ability to expand our products and markets, and grow our business in
response to changing technologies, user, and advertiser demands, and competitive pressures. In some circumstances, we may determine to do so through the acquisition of complementary businesses and technologies rather than through internal
development, including, for example, our acquisition of Movity, Inc., a geographic data company. The identification of suitable acquisition candidates can be difficult, time-consuming, and costly, and we may not be able to successfully complete
identified acquisitions. The risks we face in connection with acquisitions include:



diversion of management time and focus from operating our business to addressing acquisition integration challenges;



coordination of research and development and sales and marketing functions;



transition of the acquired companys users to our website and mobile applications;



retention of employees from the acquired company;



cultural challenges associated with integrating employees from the acquired company into our organization;



failure to successfully continue the development of acquired technology;

the need to implement or improve controls, procedures, and policies at a business that prior to the acquisition may have lacked effective controls,
procedures, and policies;



liability for activities of the acquired company before the acquisition, including patent and trademark infringement claims, violations of laws,
commercial disputes, tax liabilities, and other known and unknown liabilities;



litigation or other claims in connection with the acquired company, including claims from terminated employees, users, former stockholders, or other
third parties;



substantial impairments to goodwill or intangible assets in the event that an acquisition proves to be less valuable than the price we paid for it; and



the possibility that any acquisition may be viewed negatively by our customers or investors or the financial markets.

Our failure to address these risks or other problems encountered in connection with our past
or future acquisitions and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments, cause us to incur unanticipated liabilities, and harm our business generally. Also, the anticipated benefits of
any acquisitions may not materialize.

Competition within our industry for acquisitions of businesses, technologies, assets
and product lines has been, and is likely to continue to be, intense. As such, even if we are able to identify an acquisition that we would like to consummate, we may not be able to complete the acquisition on commercially reasonable terms or
because the target chooses to be acquired by another company. Furthermore, in the event that we are able to identify and consummate any future acquisitions, we may, in each of those acquisitions:



issue equity securities which would dilute current stockholders percentage ownership;



incur substantial debt to finance the acquisition or assume substantial debt in the acquisition;



incur significant acquisition-related expenses;



assume substantial liabilities, contingent or otherwise; or



expend significant cash.

These financing activities or expenditures could harm our operating results, cash flows, and financial condition or the price of our common stock. Alternatively, due to difficulties in the capital or
credit markets, we may be unable to secure capital on reasonable terms, or at all, necessary to complete an acquisition.

A significant
disruption in service on our website or of our mobile applications could damage our reputation and result in a loss of users of our products and of advertisers, which could harm our business, operating results, and financial condition.

Our brand, reputation, and ability to attract users and advertisers depend on the reliable performance of our network
infrastructure and content delivery. We may experience significant interruptions with our systems in the future. Interruptions in these systems, whether due to system failures, computer viruses, or physical or electronic break-ins, could affect the
security or availability of our products on our website and mobile applications, and prevent or inhibit the ability of users to access our products. Problems with the reliability or security of our systems could harm our reputation, result in a loss
of users of our products and of advertisers, and result in additional costs.

Substantially all of the communications,
network, and computer hardware used to operate our website and mobile applications is located at a single colocation facility in Santa Clara, California. While we have made investments to back up our system in the event of a disruption involving
this facility, our systems are not fully redundant. In addition, we do not own or control the operation of this facility. Our systems and operations are vulnerable to damage or interruption from fire, flood, power loss, telecommunications failure,
terrorist attacks, acts of war, electronic and physical break-ins, computer viruses, earthquakes, and similar events. The occurrence of any of these events could result in damage to our systems and hardware or could cause them to fail.

Problems faced by our third-party web hosting providers could adversely affect the experience of our users. Our third-party web hosting
providers could close their facilities without adequate notice. Any financial difficulties, up to and including bankruptcy, faced by our third-party web hosting providers or any of the service providers with whom they contract may have negative
effects on our business, the nature and extent of which are difficult to predict. If our third-party web hosting providers are unable to keep up with our growing capacity needs, our business could be harmed.

Any errors, defects, disruptions, or other performance or reliability problems with our network operations could cause interruptions in
access to our products as well as delays and additional expense in arranging new facilities and services and could harm our reputation, business, operating results, and financial condition.

Our failure to protect confidential information of our users against security breaches could damage
our reputation and brand and harm our business and operating results.

We maintain sensitive information provided by
users and advertisers. We rely on encryption and authentication technology licensed from third parties to effect secure transmission of confidential information, including personally identifiable information and credit card numbers. We may need to
expend significant resources to protect against security breaches or to address problems caused by breaches. If we are unable to maintain the security of confidential information that is provided to us by our users, our reputation and brand could be
harmed and we may be exposed to a risk of loss or litigation and possible liability, any of which could harm our business and operating results.

Our business depends on our intellectual property, the protection of which is crucial to the success of our business. We rely on a combination of patent, trademark, trade secret, and copyright law and
contractual restrictions to protect our intellectual property. In addition, we attempt to protect our intellectual property, technology, and confidential information by requiring our employees and consultants to enter into confidentiality and
assignment of inventions agreements and third parties to enter into nondisclosure agreements. These agreements may not effectively prevent unauthorized use or disclosure of our confidential information, intellectual property, or technology and may
not provide an adequate remedy in the event of unauthorized use or disclosure of our confidential information, intellectual property, or technology. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy
aspects of our website features, software, and functionality or obtain and use information that we consider proprietary.

We
have registered Trulia as a trademark in the United States, the European Union and Canada. Competitors may adopt service names similar to ours, thereby harming our ability to build brand identity and possibly leading to user confusion.
In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of the term Trulia.

We currently hold the Trulia.com Internet domain name and various other related domain names. The regulation of domain names
in the United States is subject to change. Regulatory bodies could establish additional top-level domains, appoint additional domain name registrars, or modify the requirements for holding domain names. As a result, we may not be able to acquire or
maintain all domain names that use the name Trulia.

Litigation or proceedings before the U.S. Patent and Trademark Office or
other governmental authorities and administrative bodies in the United States and abroad may be necessary in the future to enforce our intellectual property rights, to protect our patent rights, trade secrets, and domain names and to determine the
validity and scope of the proprietary rights of others. Our efforts to enforce or protect our proprietary rights may be ineffective and could result in substantial costs and diversion of resources, which could harm our business and operating
results.

Intellectual property infringement assertions by third parties could result in significant costs and harm our business and
operating results.

Other parties have asserted, and may in the future assert, that we have infringed their
intellectual property rights. Such litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue, and therefore our own issued and pending patents may provide little or no deterrence. We could
also be required to pay damages in an unspecified amount. For example, in September 2011, we entered into a settlement agreement with CIVIX-DDI LLC, or CIVIX, relating to a claim by CIVIX that we infringed two CIVIX patents relating to searching and
locating real estate. Under the settlement agreement, we agreed to pay CIVIX to settle the litigation.

In addition, on September 12, 2012, Zillow, Inc., or Zillow, filed a lawsuit against us
in the United States District Court for the Western District of Washington, alleging that we infringe on one U.S. patent held by it. The lawsuit alleges that one component of our Trulia Estimates feature infringes upon Zillows patent
insofar as Trulia Estimates allows homeowners to claim their homes and provide additional information about the properties, which enables us to update the valuation estimates for such properties. We started offering our Trulia
Estimates feature in 2011. Zillow is seeking a permanent injunction against the alleged infringement, compensatory damages, and attorneys fees. We filed a motion to dismiss Zillows complaint on December 19, 2012. The court
deferred ruling on our motion to dismiss because the Federal Circuit Court of Appeals is expected to soon provide guidance on the question raised in our motion.

On January 10, 2013, Mortgage Grader, Inc., or Mortgage Grader, filed a lawsuit against us in the United States District Court for the Central District of California, alleging that we infringe on two
U.S. patents held by it. The lawsuit alleges that our mortgage center infringes its patents insofar as we provide a method of assisting borrowers in obtaining mortgage loans. Mortgage Grader is seeking an injunction against the alleged infringement,
compensatory damages, and attorneys fees.

The foregoing litigation matters could cause us to incur significant expenses
and costs. In addition, the outcome of any litigation is inherently unpredictable, and as a result of these litigation matters, we may be required to pay damages, an injunction may be entered against us that requires us to change certain features in
our marketplace, or a license or other right to continue to deliver an unmodified version of such features may not be made available to us at all or may require us to pay ongoing royalties and comply with unfavorable terms. Any of these outcomes
could harm our business. Even if we were to prevail, these litigation matters could be costly and time-consuming, could divert the attention of our management and key personnel from our business operations, and may discourage consumers, real estate
professionals, and advertisers from using our marketplace.

From time to time, we also have other claims brought against us by
third parties alleging infringement of their intellectual property. We cannot predict whether other assertions of third-party intellectual property rights or claims arising from such assertions will substantially harm our business and operating
results. The defense of these claims and any future infringement claims, whether they are with or without merit or are determined in our favor, may result in costly litigation and diversion of technical and management personnel. Furthermore, an
adverse outcome of a dispute may require us to pay damages, potentially including treble damages and attorneys fees, if we are found to have willfully infringed a partys patent or copyright rights; cease making, licensing or using
products that are alleged to incorporate the intellectual property of others; expend additional development resources to redesign our products; and enter into potentially unfavorable royalty or license agreements in order to obtain the right to use
necessary technologies. Royalty or licensing agreements, if required, may be unavailable on terms acceptable to us, or at all. In any event, we may need to license intellectual property which would require us to pay royalties or make one-time
payments. Even if these matters do not result in litigation or are resolved in our favor or without significant cash settlements, the time and resources necessary to resolve them could harm our business, operating results, financial condition, and
reputation.

Valuation and other proprietary data may be subject to disputes.

We provide data that is relevant to the decision to purchase a home and some of this data is subject to revision, interpretation, or
dispute. For example, our Trulia Estimates tool provides users with home valuations and is based on algorithms we have developed to analyze third-party data. We revise our algorithms regularly, which may cause valuations to differ from
those previously provided. Consumers and real estate professionals sometimes disagree with our estimates. Any such variation in or disagreements about the estimates that we present could result in negative user feedback, harm our reputation, or lead
to legal disputes.

We are subject to payments-related risks.

We accept payments using a variety of methods, including credit and debit cards. For certain payment methods, including credit and debit
cards, we pay bank interchange and other fees, which may increase over time

and raise our operating costs and lower profitability. We rely on third parties to provide payment processing services, including the processing of credit and debit cards, and our business would
be disrupted if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements, and rules governing electronic funds transfers, which could
change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card
payments from consumers or facilitate other types of online payments, and our business and operating results could be adversely affected.

Our business is subject to a variety of state and federal laws, many of which are unsettled and still developing and which could subject us to
claims or otherwise harm our business.

We are subject to a variety of federal and state laws, including laws regarding
data retention, privacy, and consumer protection, that are continuously evolving and developing. The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting. For example, laws relating to
the liability of providers of online services for activities of their users and other third parties are currently being tested by a number of claims, including actions based on invasion of privacy and other torts, unfair competition, copyright and
trademark infringement, and other theories based on the nature and content of the materials searched, the ads posted, or the content provided by users. In addition, regulatory authorities are considering a number of legislative and regulatory
proposals concerning data protection and other matters that may be applicable to our business. Changes to existing laws or regulations or the adoption of new laws or regulations could negatively affect our business. It is difficult to predict how
existing laws will be applied to our business and the new laws to which we may become subject.

If we are unable to implement and
maintain effective internal control over financial reporting in the future, the accuracy, and timeliness of our financial reporting may be adversely affected.

The Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and the effectiveness of
our disclosure controls and procedures quarterly. If we are not able to comply with the requirements of the Sarbanes-Oxley Act in a timely manner, the market price of our stock could decline and we could be subject to sanctions or investigations by
the New York Stock Exchange, the SEC, or other regulatory authorities, which would require additional financial and management resources. In connection with the audit of our financial statements for 2009, 2010, and 2011, we identified a material
weakness in the design and operating effectiveness of our internal control over financial reporting that was the result of a lack of a sufficient number of qualified personnel within our accounting department that possessed an appropriate level of
expertise to perform certain accounting functions. A material weakness is a deficiency, or a combination of deficiencies, that creates a reasonable possibility that a material misstatement of a companys annual or interim financial statements
will not be prevented or detected on a timely basis.

Although we have remediated this material weakness, we cannot assure you
that there will not be material weaknesses in our internal control over financial reporting in the future.

We have not
performed an evaluation of our internal control over financial reporting, such as required by Section 404 of the Sarbanes-Oxley Act, nor have we engaged our independent registered public accounting firm to perform an audit of our internal
control over financial reporting as of any balance sheet date or for any period reported in our financial statements. Had we performed such an evaluation or had our independent registered public accounting firm performed an audit of our internal
control over financial reporting, control deficiencies, including material weaknesses and significant deficiencies, may have been identified. In addition, we are an emerging growth company as defined in the Jumpstart Our Business
Startups Act, and as such we may elect to avail ourselves of the exemption from the requirement that our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley
Act until we cease to

be an emerging growth company. See We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure
requirements applicable to emerging growth companies could make our common stock less attractive to investors, for additional risks relating to our emerging growth company status.

If we are unable to maintain effective internal control over financial reporting to meet the demands placed upon us as a public company,
including the requirements of the Sarbanes-Oxley Act, we may be unable to accurately report our financial results, or report them within the timeframes required by law or exchange regulations.

Complying with the laws and regulations affecting public companies has increased and may continue to increase our costs and the demands on
management and could harm our operating results.

As a public company, we have incurred and expect to continue to incur
significant legal, accounting, and other expenses. In addition, the Sarbanes-Oxley Act and rules subsequently implemented by the SEC and the New York Stock Exchange impose various requirements on public companies, including requiring changes in
corporate governance practices. Our management and other personnel have devoted and will need to continue to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased and will continue
to increase our legal, accounting, and financial compliance costs and have made and will continue to make some activities more time-consuming and costly. These rules and regulations could also make it more difficult for us to attract and retain
qualified persons to serve on our board of directors or our board committees or as executive officers.

In addition, the
Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and the effectiveness of our disclosure controls and procedures quarterly. In particular, beginning with the
year ending December 31, 2013, we will need to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on, and our independent registered public accounting firm
potentially to attest to, the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, or Section 404. As an emerging growth company we may elect to avail ourselves
of the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act. However, we may no longer
avail ourselves of this exemption when we cease to be an emerging growth company and, when our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the
cost of our compliance with Section 404 will correspondingly increase. Our compliance with applicable provisions of Section 404 will require that we incur substantial accounting expense and expend significant management time on
compliance-related issues as we implement additional corporate governance practices and comply with reporting requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if
we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to
sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this could cause a decline in the market price of our stock. Irrespective of compliance with Section 404,
any failure of our internal control over financial reporting could have a material adverse effect on our stated operating results and harm our reputation. If we are unable to implement these changes effectively or efficiently, it could harm our
operations, financial reporting, or financial results and could result in an adverse opinion on internal control from our independent registered public accounting firm.

We are an emerging growth company, and any decision on our part to comply only with
certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act enacted in April 2012, and, for as long as we continue to be an emerging growth company, we
may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies, including, but not limited to, not being required to have our independent
registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and
exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company until
December 31, 2017; however, if we have more than $1.0 billion in annual revenue, if the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30 of any year, or we issue more than $1.0 billion of
non-convertible debt over a three-year period before the end of that five-year period, we would cease to be an emerging growth company as of the following December 31. We cannot predict if investors will find our common stock less
attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our common stock and our stock price
may be more volatile.

Under the Jumpstart Our Business Startups Act, emerging growth companies can delay adopting new or
revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and, therefore, we will be subject to the same
new or revised accounting standards as other public companies that are not emerging growth companies.

We have pledged substantially all
of our assets to secure indebtedness.

On September 15, 2011, we entered into a loan and security agreement with
Hercules Technology Growth Capital, Inc., or Hercules, providing for a secured term loan facility, or the credit facility, in an aggregate principal amount of up to $20.0 million to be used for general business purposes. Indebtedness we incur under
this agreement is secured by substantially all of our assets. This agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our ability to, among other things, incur additional indebtedness, grant
liens, make investments, repurchase stock, pay dividends, transfer assets, merge or consolidate, and make acquisitions. In May 2012, we failed to comply with the covenant that required delivery of audited financial statements for the year ended
December 31, 2011 within the time period set forth in the credit facility. Hercules granted a waiver arising from our failure to comply with this reporting covenant. If we default on our obligations under this agreement, Hercules may foreclose
on our assets to repay our outstanding obligations to Hercules, which would materially and adversely impact our business. As of December 31, 2012, we had drawn $10.0 million in term loans under the credit facility, and the drawdown period for
the remaining $10.0 million expired. If we default on payments due pursuant to the credit facility and are forced to sell assets to satisfy these obligations, our business would be materially and adversely affected.

Our operating results may be harmed if we are required to collect sales taxes for our products.

There is general uncertainty in the industry about the obligation of Internet-based businesses to collect and remit sales taxes in
jurisdictions where their commerce is solely virtual. In the current climate, it is possible that one or more states or countries could seek to impose sales or other tax collection obligations on us or our subscribers with regards to our products,
which taxes may be applicable to past sales. A successful assertion that we should be collecting additional sales or other taxes on our products could result in substantial tax liabilities for past sales, discourage subscribers from purchasing our
products, or otherwise harm our business and operating results.

If we fail to expand effectively into adjacent markets, our growth prospects could be harmed.

We intend to expand our operations into adjacent markets, such as rentals, mortgages, and home improvement, and into
international geographies. We may incur losses or otherwise fail to enter these markets successfully. Our expansion into these markets will place us in competitive environments with which we are unfamiliar and involves various risks, including the
need to invest significant resources and the possibility that returns on such investments will not be achieved for several years, or at all. In attempting to establish a presence in new markets, we expect to incur significant expenses and face
various other challenges, such as expanding our sales force and management personnel to cover these markets. For example, in September 2012, we introduced a mortgage product through which we provide real-time mortgage quotes to our users. We
currently obtain mortgage quotes from a single third-party partner. While the third-party partner is obligated under our agreement to continue to provide real-time mortgage quotes and to support us until August 2013, it has notified us that it will
be terminating this agreement in August 2013. If we are unable to add additional real-time mortgage quote providers, find replacement real-time mortgage quote providers on similar or better terms or we are unable to integrate with other providers,
our expansion into the mortgage market will be hindered and our business and operating results may suffer.

We may require additional
capital to support business growth, and this capital might not be available on acceptable terms, if at all.

We intend
to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new features and products or enhance our existing products, improve our operating
infrastructure, or acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. Our existing stockholders will suffer dilution as a result of this offering and, if we
raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant ownership dilution, and any new equity securities we issue could have rights, preferences, and privileges
superior to those of holders of our common stock. Any debt financing we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult
for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or
financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be impaired, and our business may be harmed.

From time to time, we have released, and may continue to release guidance in our quarterly earnings conference call, quarterly earnings releases, or otherwise, regarding our future performance that
represents our managements estimates as of the date of release. This guidance, which includes forward-looking statements, has been and will be based on projections prepared by our management. These projections are not prepared with a view
toward compliance with published guidelines of the American Institute of Certified Public Accountants, and neither our registered public accountants nor any other independent expert or outside party compiles or examines the projections. Accordingly,
no such person expresses any opinion or any other form of assurance with respect to the projections.

Projections are based
upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic, and competitive uncertainties and contingencies, many of which are beyond our control and are
based upon specific assumptions with respect to future business decisions, some of which will change. We intend to state possible outcomes as high and low ranges which are intended to provide a sensitivity analysis as variables are changed but are
not intended to imply that actual results could not fall outside of the suggested ranges. The principal reason that we release guidance is

to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such third
parties.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying
the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results may vary from our
guidance and the variations may be material. In light of the foregoing, investors are urged not to rely upon our guidance in making an investment decision regarding our common stock.

Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this
Risk Factors section in this prospectus could result in the actual operating results being different from our guidance, and the differences may be adverse and material.

Concentration of ownership among our existing executive officers, directors, and their affiliates may prevent new investors from influencing significant corporate decisions.

As of February 28, 2013, and after giving effect to the completion of this offering, our executive officers, directors, and holders of 5%
or more of our outstanding common stock will beneficially own, in the aggregate, approximately 50.2% of our outstanding shares of common stock. Some of these persons or entities may have interests that are different from yours. For example, these
stockholders may support proposals and actions with which you may disagree or which are not in your interests. These stockholders will be able to exercise a significant level of control over all matters requiring stockholder approval, including the
election of directors, amendment of our certificate of incorporation, and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of our company or changes in management and
will make the approval of certain transactions difficult or impossible without the support of these stockholders, which in turn could reduce the price of our common stock.

The price of our common stock may be volatile, and you could lose all or part of your investment.

The trading price of our common stock has fluctuated and may continue to fluctuate substantially. Since shares of our common stock were sold in our initial public offering, or the IPO, in September 2012
at a price of $17.00 per share, the reported high and low sales prices of our common stock have ranged from $14.69 to $38.22 through March 8, 2013. The trading price of our common stock depends on a number of factors, including those described
in this Risk Factors section, many of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose all or part of your investment in our common stock since you might be
unable to sell your shares at or above the price you paid in this offering. Factors that could cause fluctuations in the trading price of our common stock include the following:



price and volume fluctuations in the overall stock market from time to time;



volatility in the market prices and trading volumes of high technology stocks;



changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;



sales of shares of our common stock by us or our stockholders;



failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company, or our
failure to meet these estimates or the expectations of investors;



the financial projections we may provide to the public, any changes in those projections, or our failure to meet those projections;



announcements by us or our competitors of new products;



the publics reaction to our press releases, other public announcements, and filings with the SEC;

conditions in the real estate industry or changes in mortgage interest rates; and



general economic conditions and slow or negative growth of our markets.

In addition, the stock market in general, and the market for technology companies in particular, have experienced extreme price and
volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may seriously affect the market price of our common stock, regardless of our actual operating
performance. In addition, in the past, following periods of volatility in the overall market and the market prices of a particular companies securities, securities class action litigations have often been instituted against these companies.
Litigation of this type, if instituted against us, could result in substantial costs and a diversion of our managements attention and resources.

A substantial majority of our total outstanding shares after the offering are restricted from immediate resale, but may be sold on a stock exchange in the near future. The large number of shares
eligible for public sale or subject to rights requiring us to register them for public sale could depress the market price of our common stock.

The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the market after this offering, and the perception that these sales could occur
may also depress the market price of our common stock. Based on 27,653,926 shares outstanding as of December 31, 2012, after giving effect to the issuance of 101,108 shares of our common stock to be acquired by certain selling stockholders
through option exercises in order to sell shares in this offering, we will have 31,153,926 shares of common stock outstanding after this offering. Of these outstanding shares, all of the 6,900,000 shares of common stock sold in our IPO and all of
the 5,250,000 shares of common stock sold in this offering are or will be freely tradable in the United States, except for any shares purchased by our affiliates as defined in Rule 144 under the Securities Act of 1933. Certain holders of
shares of outstanding common stock or securities convertible into or exchangeable for common stock have agreed with the underwriters of our IPO, subject to certain exceptions, not to dispose of or hedge any of their common stock before
March 19, 2013, except with the prior written consent of J.P. Morgan Securities LLC and Deutsche Bank Securities Inc. However, on February 22, 2013, as a result of the early release feature of these lock-up agreements with the
underwriters, except for the lock-up agreements with our executive officers, 25% of each holders shares of our common stock that were subject to the agreement with the underwriters became available for sale in the public market in the United
States, subject to prior registration in the United States, if required, or reliance upon an exemption from United States registration, including in the case of shares held by affiliates or control persons, compliance with the volume restrictions of
Rule 144. This early release was triggered because the closing price of our common stock on the New York Stock Exchange was equal to or greater than $23.80 for 20 out of 30 trading days ending on or after December 18, 2012. This early release
was not included in the lock-up agreements between each of our executive officers and the underwriters.

Beginning on March 19, 2013, the balance of these shares may be sold in the public market in the United States, subject to prior registration in the United States, if required, or reliance
upon an exemption from registration, including, in the case of shares held by affiliates or control persons, compliance with the volume restrictions of Rule 144.

Additionally, our officers, directors, and certain holders of shares of outstanding common stock or securities convertible into or exchangeable for common stock have agreed with the underwriters of this
offering, subject to certain exceptions, not to dispose of or hedge any of their common stock during the period ending 45 days after the date of this prospectus, except with the prior written consent of Deutsche Bank Securities Inc. and J.P. Morgan
Securities LLC. Shares of common stock or securities convertible into or exchangeable for common stock that were released from the lock-up agreement with the underwriters of our IPO on February 22, 2013 are not subject to the lock-up agreement with
the underwriters in connection with this offering. After the expiration of this restricted period, these shares may be sold in the public market in the United States, subject to prior registration in the United States, if required, or reliance upon
an exemption from United States registration, including, in the case of shares held by affiliates or control persons, compliance with the volume restrictions of Rule 144.

As a result of these agreements and the provisions of our investor rights agreement described under the section titled Description of Capital StockRegistration Rights, subject to the
provisions of Rule 144 or Rule 701, shares will be available for sale in the public market as follows:



12,150,000 shares sold in this offering and in our IPO will be immediately available for sale in the public market;



4,610,005 shares which are not subject to the lock-up agreement in connection with this offering became eligible for sale on February 22, 2013 in
the public market as a result of the triggering of the early release feature of the lock-up agreements entered into in connection with our IPO or the partial release of market standoff agreements with us;



2,431,695 shares which are not subject to the lock-up agreement in connection with this offering (excluding 4,610,005 shares that were early released
pursuant to the terms of the IPO lock-up agreement on February 22, 2013 or were partially released from market standoff agreements with us) will be eligible for sale on March 19, 2013 in the public market upon the expiration of lock-up
agreements entered into in connection with our IPO and market standoff agreements with us; and



11,962,226 shares will be eligible for sale in the public market upon the expiration of lock-up agreements entered into in connection with this
offering.

As of February 28, 2013, after giving effect to the sale by existing holders of
registration rights of 1,648,892 shares in this offering, an aggregate of 10,289,283 shares are entitled, under contracts providing for registration rights, to require us to register shares of our common stock owned by them for public sale in the
United States. In addition, we filed a registration statement to register the 6,112,904 shares that have been issued or are reserved for future issuance under our equity compensation plans. Subject to the satisfaction of applicable exercise periods
and, in certain cases, lock-up agreements with the representatives of the underwriters referred to above, the shares of common stock issued upon exercise of outstanding options will be available for immediate resale in the United States in the open
market.

Sales of our common stock as restrictions end or pursuant to registration rights may make it more difficult for
us to sell equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause our stock price to fall and make it more difficult for you to sell shares of our common stock.

Anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could impair a takeover
attempt.

Our certificate of incorporation, bylaws, and Delaware law contain provisions which could have the effect of
rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our board of directors. Our corporate governance documents include provisions:



providing for a classified board of directors whose members serve staggered three-year terms;

authorizing blank check preferred stock, which could be issued by our board of directors without stockholder approval and may contain
voting, liquidation, dividend, and other rights superior to our common stock;

limiting the ability of our stockholders to call and bring business before special meetings;



requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for
election to our board of directors;



controlling the procedures for the conduct and scheduling of board of directors and stockholder meetings; and



providing our board of directors with the express power to postpone previously scheduled annual meetings and to cancel previously scheduled special
meetings.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in
control or changes in our management.

As a Delaware corporation, we are also subject to provisions of Delaware law, including
Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of substantially all of
our outstanding common stock.

Any provision of our certificate of incorporation, bylaws or Delaware law that has the effect
of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

We may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a return.

We currently intend to use the net proceeds from the sale of shares of common stock by us in this offering for working
capital and other general corporate purposes, and expect to use some or all of such net proceeds to acquire complementary businesses, products, services, or technologies. However, we do not have any agreements or commitments for any acquisitions at
this time. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net
proceeds may be invested with a view towards long-term benefits for our stockholders and this may not increase our operating results or market value. Until the net proceeds are used, they may be placed in investments that do not produce significant
income or that may lose value.

Purchasers in this offering will experience immediate and substantial dilution in the book value of
their investment.

The assumed public offering price of our common stock of $30.44 per share, which is the last
reported sale price of our common stock on the New York Stock Exchange on March 8, 2013, is substantially higher than the net tangible book value per share of our outstanding common stock immediately after this offering. Therefore, if you
purchase our common stock in this offering, you will incur immediate dilution of $24.50 in the net tangible book value per share from the price you paid. In addition, following this offering, purchasers who bought shares from us in this offering
will have contributed 46% of the total consideration paid to us by our stockholders to purchase shares of common stock, in exchange for acquiring approximately 11% of our total outstanding shares as of December 31, 2012 after giving effect to
this offering. The exercise of outstanding stock options and warrants and the vesting of outstanding restricted stock units will result in further dilution.

If securities or industry analysts do not publish or cease publishing research or reports about us,
our business or our market, or if they change their recommendations regarding our stock adversely, our stock price and trading volume could decline.

The trading market for our common stock has been and may continue to be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market, or our
competitors. If any of the analysts who covers us change their recommendation regarding our stock adversely, or provide more favorable relative recommendations about our competitors, our stock price would likely decline. If any analyst who covers us
were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

We do not expect to declare any dividends in the foreseeable future.

We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. In addition, the terms of our
credit facility currently prohibit us from paying cash dividends on our capital stock. Consequently, investors may need to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future
gains on their investment. Investors seeking cash dividends should not purchase our common stock.

This prospectus contains forward-looking statements within the meaning of the federal securities laws, which
statements involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or our future financial or operating performance. In some cases, you can identify forward-looking statements because they contain
words such as may, will, should, expects, plans, anticipates, could, intends, target, projects, contemplates,
believes, estimates, predicts, potential or continue or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions.
Forward-looking statements contained in this prospectus include, but are not limited to, statements about:

the continued availability of home listing and other information relevant to the real estate industry;



the growth in the usage of our mobile applications and our ability to successfully monetize this usage;



our ability to innovate and provide a superior user experience;



our ability to capitalize on strategic and adjacent opportunities;



the effects of the market for real estate and general economic conditions on our business; and



the attraction and retention of qualified employees and key personnel.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this prospectus.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements
contained in this prospectus primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations, and prospects. The outcome of the events described
in these forward-looking statements is subject to risks, uncertainties, and other factors described in the section titled Risk Factors and elsewhere in this prospectus. Moreover, we operate in a very competitive and rapidly changing
environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this prospectus. We cannot assure you
that the results, events, and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements made in this prospectus relate only to events as of the date on which the statements are made.
We undertake no obligation to update any forward-looking statements made in this prospectus to reflect events or circumstances after the date of this prospectus or to reflect new information or the occurrence of unanticipated events, except as
required by law. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect
the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments we may make.

This prospectus also contains statistical data, estimates, and forecasts that are based on
independent industry publications, such as those published by Borrell Associates, the National Association of Realtors, and the Real Estate Book, or other publicly available information, as well as other information based on our internal sources.
Although we believe that the third-party sources referred to in this prospectus are reliable, neither we nor the underwriters have independently verified the information provided by these third parties. While we are not aware of any misstatements
regarding any third-party information presented in this prospectus, their estimates, in particular, as they relate to projections, involve numerous assumptions, are subject to risks and uncertainties, and are subject to change based on various
factors, including those discussed under the section titled Risk Factors and elsewhere in this prospectus.

The proceeds to us from the sale of shares of our common stock that we are selling in this offering will be approximately
$100.3 million, based upon an assumed public offering price of $30.44 per share, which is the last reported sale price of our common stock on the New York Stock Exchange on March 8, 2013, after deducting estimated underwriting discounts and
commissions and estimated offering expenses payable by us. If the underwriters option to purchase additional shares from us and certain selling stockholders is exercised in full, our net proceeds would be approximately $115.4 million,
after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any proceeds from the sale of shares of our common stock by the selling stockholders.

We currently intend to use the net proceeds that we will receive from this offering for working capital and other general corporate
purposes, and expect to use some or all of such net proceeds to acquire or invest in complementary businesses, products, services, technologies, or other assets. We have not entered into any agreements or commitments with respect to any acquisitions
or investments at this time.

We cannot specify with certainty the particular uses of the net proceeds that we will receive
from this offering. Accordingly, we will have broad discretion in using these proceeds. Pending the use of proceeds from this offering as described above, we plan to invest the net proceeds that we receive in this offering in short-term and
intermediate-term interest-bearing obligations, investment-grade investments, certificates of deposit, or direct or guaranteed obligations of the U.S. government.

MARKET PRICE OF COMMON STOCK

Our common stock
has been listed on the New York Stock Exchange under the symbol TRLA since September 20, 2012. Prior to that date, there was no public trading market for our common stock. The following table sets forth for the periods indicated the
high and low sales prices per share of our common stock as reported on the New York Stock Exchange:

On March 8, 2013, the last reported sale price of our common stock on the New York Stock
Exchange was $30.44 per share. As of December 31, 2012, we had 185 holders of record of our common stock. The actual number of stockholders is greater than this number of record holders and includes stockholders who are beneficial owners but
whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

DIVIDEND POLICY

We have never declared or paid any cash dividend on our capital stock. We currently intend to retain any future earnings and do not expect to pay any dividends in the foreseeable future. Any future
determination to declare cash dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on a number of factors, including our financial condition, results of operations, capital requirements,
contractual restrictions, general business conditions, and other factors that our board of directors may deem relevant. In addition, the terms of our credit facility currently prohibit us from paying cash dividends on our capital stock.

If you invest in our common stock in this offering, your ownership interest will be diluted to the extent of the difference between the
public offering price per share of our common stock and the pro forma net tangible book value per share of our common stock immediately after this offering. Net tangible book value dilution per share to new investors represents the difference
between the amount per share paid by purchasers of shares of common stock in this offering and the pro forma net tangible book value per share of common stock immediately after completion of this offering.

Net tangible book value per share is determined by dividing our total tangible assets less our total liabilities by the number of shares
of common stock outstanding. Our historical net tangible book value as of December 31, 2012 was $84.4 million, or $3.06 per share. After giving effect to the sale of 3,500,000 shares of common stock by us at the public offering price of $30.44
per share, which is the last reported sales price of our common stock on the New York Stock Exchange on March 8, 2013, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, as well as
the issuance of 101,108 shares of our common stock to be acquired by certain selling stockholders through option exercises in order to sell those shares in this offering, our pro forma net tangible book value at December 31, 2012 would have
been approximately $185.0 million, or $5.94 per share. This would represent an immediate increase in the net tangible book value of $2.88 per share to existing stockholders and an immediate dilution of $24.50 per share to investors in this offering.
The following table illustrates this per share dilution:

Each $1.00 increase or decrease in the assumed public offering price of $30.44 per share, which
is the last reported sale price of our common stock on the New York Stock Exchange on March 8, 2013, would increase or decrease, as applicable, our pro forma net tangible book value per share to new investors by $0.10, and would increase or
decrease, as applicable, dilution per share to new investors in this offering by $0.10, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting
discounts and commissions payable by us. In addition, to the extent any outstanding options or warrants to purchase common stock are exercised or any outstanding restricted stock units have vested, new investors would experience further dilution. If
the underwriters exercise their option to purchase additional shares from us and certain selling stockholders in full, the pro forma net tangible book value per share of our common stock immediately after this offering would be $6.32 per share, and
the dilution in pro forma net tangible book value per share to new investors in this offering would be $24.12 per share.

The following table presents, on a pro forma basis as of December 31, 2012, the
differences between the existing stockholders and the new investors purchasing shares of our common stock in this offering with respect to the number of shares purchased from us, the total consideration paid or to be paid to us, which includes net
proceeds received from the issuance of common stock, cash received from the exercise of stock options, and the average price per share paid or to be paid to us at the public offering price of $30.44 per share, before deducting underwriting discounts
and commissions and estimated offering expenses payable by us (and includes 101,108 shares of our common stock to be acquired by certain selling stockholders through option exercises in order to sell those shares in this offering):

Each $1.00 increase or decrease in the assumed public offering price of $30.44 per share, which
is the last reported sale price of our common stock on the New York Stock Exchange on March 8, 2013, would increase or decrease, as applicable, the total consideration paid by new investors and total consideration paid by all stockholders by
approximately $3.5 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions payable by us. In addition,
to the extent any outstanding options or warrants to purchase common stock are exercised or any outstanding restricted stock units have vested, new investors will experience further dilution.

The number of shares of common stock that will be outstanding after this offering is based on 27,653,926 shares outstanding as of
December 31, 2012, after giving effect to the issuance of 101,108 shares of our common stock to be acquired by certain selling stockholders through option exercises in order to sell those shares in this offering, and excludes:



3,469,458 shares of common stock issuable upon the exercise of options to purchase common stock that were outstanding as of December 31, 2012
(which does not include 101,108 shares to be sold in this offering by certain selling stockholders upon the exercise of options), with a weighted average exercise price of $6.54 per share;



360,938 shares of common stock issuable upon the exercise of options to purchase common stock that were granted after December 31, 2012, with a
weighted average exercise price of $26.93 per share;



37,760 shares of common stock issuable upon the vesting of restricted stock units outstanding as of December 31, 2012;



512,064 shares of common stock issuable upon the vesting of restricted stock units granted after December 31, 2012;



Up to 56,054 shares of common stock issuable upon the exercise of a warrant to purchase common stock that was outstanding as of December 31, 2012,
with an exercise price of $8.47 per share, which warrant was net exercised in February 2013 for an aggregate of 39,205 shares of common stock; and



2,123,547 shares of common stock reserved as of December 31, 2012 for future issuance under our 2012 Equity Incentive Plan (of which 873,002
shares are issuable or will be issuable upon the exercise of options or vesting of restricted stock units granted after December 31, 2012), which contains provisions that automatically increase its share reserve each year and provides for an
increase of up to 1,000,000 shares from the expiration or termination of awards under our 2005 Stock Incentive Plan.

The following table sets forth cash and cash equivalents and short-term investments, as well as our capitalization, as of
December 31, 2012 as follows:



on an actual basis; and



on a pro forma basis, giving effect to (i) the sale and issuance by us of 3,500,000 shares of common stock in this offering, at an assumed public
offering price of $30.44 per share, which is the last reported sale price of our common stock on the New York Stock Exchange on March 8, 2013, after deducting estimated underwriting discounts and commissions and estimated offering expenses
payable by us, and (ii) option exercises by certain selling stockholders in order to sell those shares in this offering.

You should read this table together with our financial statements and related notes, and the sections titled Selected Financial and Other Data and Managements Discussion and
Analysis of Financial Condition and Results of Operations that are included elsewhere in this prospectus.

Each $1.00 increase or decrease in the assumed public offering price of $30.44 per share, which
is the last reported sale price of our common stock on the New York Stock Exchange on March 8, 2013, would increase or decrease, as applicable, our cash and cash equivalents and short-term investments, additional paid-in capital, and total
stockholders equity by approximately $3.3 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and
commissions payable by us.

If the underwriters option to purchase additional shares from us were exercised in
full, pro forma cash and cash equivalents and short-term investments, additional paid-in capital, total stockholders equity and shares outstanding as of December 31, 2012 would be $215.8 million, $249.4 million,
$202.3 million and 31,678,926, respectively.

The pro forma column in the table above excludes the following:



3,469,458 shares of common stock issuable upon the exercise of options to purchase common stock that were outstanding as of December 31, 2012
(which does not include 101,108 shares to be sold in this offering by certain selling stockholders upon the exercise of options), with a weighted average exercise price of $6.54 per share;

360,938 shares of common stock issuable upon the exercise of options to purchase common stock that were granted after December 31, 2012, with a

512,064 shares of common stock issuable upon the vesting of restricted stock units granted after December 31, 2012;



Up to 56,054 shares of common stock issuable upon the exercise of a warrant to purchase common stock that was outstanding as of December 31,
2012, with an exercise price of $8.47 per share, which warrant was net exercised in February 2013 for an aggregate of 39,205 shares of common stock; and



2,123,547 shares of common stock reserved as of December 31, 2012 for future issuance under our 2012 Equity Incentive Plan (of which 873,002 shares are
issuable or will be issuable upon the exercise of options or vesting of restricted stock units granted after December 31, 2012), which contains provisions that automatically increase its share reserve each year and provides for an increase of up to

Non-GAAP Financial Measures

Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles in the United States, or GAAP. We define Adjusted EBITDA as net loss adjusted to
exclude interest income, interest expense, taxes, depreciation and amortization, change in the fair value of our warrant liability and stock-based compensation. Below, we have provided a reconciliation of Adjusted EBITDA to our net loss, the most
directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any other measure of financial performance calculated and presented in accordance with
GAAP. Our Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate Adjusted EBITDA in the same manner as we calculate the measure.

We include Adjusted EBITDA in this prospectus because it is an important measure upon which our management assesses our operating
performance. We use Adjusted EBITDA as a key performance measure because we believe it facilitates operating performance comparisons from period to period by excluding potential differences primarily caused by variations in capital structures, tax
positions, the impact of depreciation and amortization expense on our fixed assets, changes related to the fair value remeasurements of our preferred stock warrant, and the impact of stock-based compensation expense. Because Adjusted EBITDA
facilitates internal comparisons of our historical operating performance on a more consistent basis, we also use Adjusted EBITDA for business planning purposes, to incentivize and compensate our management personnel, and in evaluating acquisition
opportunities. In addition, we believe Adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance and
debt-service capabilities.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not
consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:



Adjusted EBITDA does not reflect our cash expenditures for capital equipment or other contractual commitments;



Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and
Adjusted EBITDA does not reflect capital expenditure requirements for such replacements;

Adjusted EBITDA does not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our
indebtedness; and



Other companies, including companies in our industry, may calculate Adjusted EBITDA measures differently, which reduces their usefulness as a
comparative measure.

In evaluating Adjusted EBITDA, you should be aware that in the future we will incur
expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating
our performance, you should consider Adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated:

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations
should be read in conjunction with the section titled Selected Financial and Other Data and financial statements and related notes thereto included elsewhere in this prospectus. This discussion contains forward-looking statements that
involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the
section titled Risk Factors included elsewhere in this prospectus.

Overview

Trulia is redefining the home search experience for consumers and changing the way that real estate professionals build their businesses.
Our marketplace, delivered through the web and mobile applications, gives consumers powerful tools to research homes and neighborhoods and enables real estate professionals to efficiently market their listings and attract new clients. We believe we
deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer products that provide real estate professionals with
access to transaction-ready consumers and help them enhance their online presence.

Key elements of our marketplace are
extensive consumer reach, an engaged base of real estate professionals and a comprehensive database of real estate information and local insights. In the year ended December 31, 2012, we had 23.1 million monthly unique visitors, and as of
December 31, 2012, we had more than 390,000 active real estate professionals, 24,443 of which were paying subscribers in our marketplace. Our large, continually refreshed, and searchable database contains more than 112 million properties,
including 4.1 million homes for sale and rent. We supplement listings data with local information on schools, crime and neighborhood amenities to provide unique insights into each community. In addition, we harness rich, insightful
user-generated content from our active community of contributors, including consumers, local enthusiasts, and real estate professionals. With more than 7 million unique user contributions, we believe we have the largest collection of
user-generated content on homes, neighborhoods, and real estate professionals. We deliver this information on mobile devices through our iPhone, iPad, Android Phone, Android Tablet, Kindle, and Windows 8 applications and also provide tailored mobile
experiences, such as GPS-based search.

We offer our products free to consumers. We deliver the inside scoop on
homes, neighborhoods, and real estate professionals in an intuitive and engaging way, helping consumers make more informed housing decisions. For real estate professionals, we offer a suite of free and subscription products to promote themselves and
their listings online, and to connect with consumers searching for homes. Our free products attract users to our marketplace and the quality of our products drives the growth of our audience and promotes deep engagement by our users. We believe this
leads real estate professionals to convert to paying subscribers and brand advertisers to purchase our advertising products.

We generate revenue primarily from sales of subscription marketing products that we offer to real estate professionals. Our Trulia Pro
product allows real estate professionals to receive prominent placement of their listings in our search results. With our Trulia Local Ads and Trulia Mobile Ads products, real estate professionals can purchase local advertising on
our website and mobile applications, respectively, by locale and by share of a given market. We also generate revenue from display advertising we sell to leading real estate advertisers and consumer brands seeking to reach our attractive audience.
Pricing for our display advertisements is based on advertisement size and position on our web page, and fees are based on a per-impression or on a per-click basis.

To date, we have focused our efforts and investments on developing and delivering superior products and user experiences, attracting consumers and real estate professionals to our marketplace, and growing
our revenue. We have invested heavily to build our robust data and analytics platform, and continue to spend significantly on technology and engineering.

In 2005, we launched the initial version of our website. Since then, we have become one of
the leading online real estate marketplaces in the United States by achieving key product development and business milestones that have driven our revenue and user growth, including:



In May 2007, we launched Trulia Voices, a forum for our users to get the inside scoop on what it is like to live in a neighborhood
from our community of contributors, including consumers, local enthusiasts, and real estate professionals;



In June 2008, we launched Trulia Pro, a premium advertising product by which real estate professionals promote their listings and market
themselves to consumers;



In August 2008, we launched our first mobile product for consumers with a home search application on the iPhone and our mobile-optimized website
m.trulia.com for consumers that is available on any mobile device browser;

In December 2010, we acquired Movity, Inc., a geographic data company, for its engineering team and its data visualization expertise;



In January 2011, we expanded our presence by opening a dedicated sales and customer service center in Denver, Colorado, increasing our headcount by 149
people;



In March 2011, we expanded our mobile products for consumers with home search applications on the iPad and Android Phone;



In December 2011, we launched Trulia for Agents on the iPhone, a mobile application dedicated to helping real estate professionals. Key features
of the application include check-ins and lead notifications;



In May 2012, we launched Trulia Mobile Ads, an innovative marketing product that allows real estate professionals to target consumers who are
researching homes on mobile devices; and



In September 2012, we launched Trulia Mortgage Center to provide personalized mortgage quotes that we update in real time.

We have experienced rapid growth in the past three years. In the years ended December 31, 2010, 2011,
and 2012, we generated revenue of $19.8 million, $38.5 million, and $68.1 million, respectively. During the same period, we had net losses of $3.8 million, $6.2 million, and $10.9 million, respectively.

Opportunities and Challenges

We believe that the growth of our business and our future success are dependent upon many factors including our ability to increase our audience size and user engagement, grow the number of subscribers in
our marketplace, increase the value of our advertising products, and successfully invest in our growth. While each of these areas presents significant opportunities for us, they also pose important challenges that we must successfully address in
order to sustain the growth of our business and improve our operating results.

Increase in Audience Size and User
Engagement. We believe that increases in audience size and user engagement would make our marketplace more attractive to real estate professionals and advertisers which could lead to additional subscriptions, higher rates for our subscription
products, more display advertising, and higher rates for display advertising. In order to increase our audience size and user engagement, we plan to continuously enhance and refresh our database of homes, to partner with third parties to add new and
relevant local content, and to develop new features, tools, and products, each of which may increase our expenses. If we are not able to increase audience size and user engagement in our marketplace, we may not be able to increase the revenue from
our subscription and display advertising products, and our operating results may be harmed.

Growth in the Number of
Subscribers in our Marketplace. We believe that we will need to further penetrate the large base of more than 2.8 million real estate professionals in the United States in order to increase our

revenues and improve our operating results. As of December 31, 2012, we had more than 390,000 active real estate professionals in our marketplace, 24,443 of whom were paying subscribers. If
we are able to increase the number of paying subscribers in our marketplace, we expect that this would increase our revenue and improve our operating results, and any failure to increase the number of paying subscribers in our marketplace would
adversely affect our revenue and operating results. To attract additional real estate professionals to our marketplace and to encourage real estate professionals to become paying subscribers, we plan to communicate the value of our free and
subscription products, to continue to offer our subscribers high-quality leads from consumers using our marketplace, to enhance and increase the ways that real estate professionals can market themselves and communicate with prospective clients in
our marketplace, and to create additional value-added products to help professionals more effectively manage their leads, documents, and other key elements of their business. We expect that our expenses will increase as we take these actions to
increase the number of real estate professionals and subscribers in our marketplace. In addition, our sales and marketing expenses were our largest operating expenses in the years ended December 31, 2011 and 2012. Sales and marketing expenses
reflect many of the costs that we incur in acquiring new subscribers and retaining existing subscribers, and we expect that sales and marketing expenses will continue to increase in absolute dollars as we seek to grow the number of subscribers in
our marketplace.

Increase Value of Advertising Products. We intend to continue to increase the attractiveness of our
display advertising products in order to increase advertiser demand and thereby increase the amount advertisers spend with us. We aim to increase the attractiveness of our advertising products through increasing the size of our audience and
engagement of our users, improving our ability to select relevant content of interest to individual users, and improving the measurement tools available to advertisers to optimize their campaigns.

Investments for Growth. We expect to continue to invest in our marketplace, our infrastructure, and our personnel in order to
drive future growth, as well as to pursue adjacent opportunities. We plan to continuously enhance and refresh our database of homes and make ongoing product enhancements intended to improve the user experience. We also expect to continue to make
investments in our technical infrastructure to ensure that our growing user base can access our marketplace rapidly and reliably. In addition, we anticipate continuing to increase our headcount to ensure that our research and development function
drives improvements in our marketplace and our sales and marketing function maximizes opportunities for growing our business and revenue. We also intend to pursue acquisitions of complementary business, products, services, or technologies to grow
our business and enhance and increase our product offerings. As part of our strategy, we also expect to invest in pursuing opportunities in large adjacent markets, such as rentals, mortgages, home improvement, and agent tools, and to expand our
business internationally. We expect that these investments will increase our operating expenses, and that any increase in revenue resulting from these investments will likely trail the increase in expenses.

Key Business Metrics

To analyze our business performance, determine financial forecasts, and help develop long-term strategic plans, we review the following key business metrics:



Monthly Unique Visitors. We count a unique visitor the first time a computer or mobile device with a unique IP address accesses our website or
our mobile applications during a calendar month. If an individual accesses our website or mobile applications using different IP addresses within a given month, the first access by each such IP address is counted as a separate unique visitor. Our
number of monthly unique visitors includes mobile monthly unique visitors. We calculate our monthly unique visitors based on the monthly average over the applicable period. We view monthly unique visitors as a key indicator of the growth in our
business and audience reach, the quality of our products, and the strength of our brand awareness. In the year ended December 31, 2012, the number of monthly unique visitors increased to 23.1 million from 14.8 million in the year
ended December 31, 2011, a 56% increase. We attribute the growth in our monthly unique visitors principally to our increasing brand awareness, the popularity of our mobile products and the overall industry trend of more consumers using the web
and mobile applications to research housing decisions.

Mobile Monthly Unique Visitors. We count a unique mobile visitor the first time a mobile device with a unique IP address accesses our website or
our mobile applications during a calendar month. We calculate our mobile monthly unique visitors based on the monthly average over the applicable period. These mobile monthly unique visitors are included in the monthly unique visitors metric. We
view mobile monthly unique visitors as a key indicator of the growth in our business and audience reach, and believe that having more unique visitors using our mobile applications will drive faster growth in our revenue. We plan to expand our mobile
products to support our rapidly growing mobile user base. In the year ended December 31, 2012, the number of mobile monthly unique visitors increased to 5.1 million from 2.1 million in the year ended December 31, 2011, a 144%
increase. We attribute this growth to the overall adoption of smartphones and the growth of mobile applications and mobile web use by consumers. We also attribute the growth in our mobile monthly unique visitors to our increased efforts in
developing a mobile website and mobile applications. Due to the significant growth rate of usage of our mobile products and solutions, our mobile monthly unique visitors has grown as a percentage of our monthly unique visitors over recent periods
and we expect this trend to continue.



New Contributions to User-Generated Content. We define user-generated content as any content contributed by a user through our website or mobile
applications, such as Q&A discussions, blogs, blog comments, user votes, recommendations, and neighborhood ratings and reviews. We view the changes in the volume of new contributions to user-generated content as a key indicator of our user
engagement and the strength of our community. In the year ended December 31, 2012, new contributions to user-generated content increased by 3.1 million contributions, and we now have over 7 million cumulative contributions on our
marketplace. We expect new contributions to user-generated content to continue to grow as our monthly unique visitors and total subscribers grow and as we introduce new features to our marketplace. While the absolute number of new contributions to
user-generated content may continue to grow period-over-period, the rate of growth has slowed and we expect that the rate of growth may continue to slow as the aggregate size of our user-generated content increases. We believe the slowing growth
rate of new contributions to user-generated content is a function of the large historical number of new contributions to user-generated content on our marketplace, which makes achievement of increasing rates of growth more challenging. We continue
to focus on promoting new contributions to user-generated content to increase the engagement of our users with our marketplace.



Total Subscribers. We define a subscriber as a real estate professional with a paid subscription at the end of a period. Total subscribers has
been, and we expect will continue to be, a key driver of revenue growth. It is also an indicator of our market penetration, the value of our products, and the attractiveness of our consumer audience to real estate professionals. As of
December 31, 2012, we had 24,443 total subscribers, a 45% increase from 16,849 total subscribers as of December 31, 2011. We attribute this growth to our increasing sales and marketing efforts, principally from the launch and growth of our
inside sales team, as well as growth in monthly unique visitors. Although our total subscribers are growing period-over-period and we expect total subscribers to continue to grow, the rate of growth may slow as we increase efforts to sell more
products to existing subscribers. In addition, subscribers often purchase subscriptions for limited periods as a result of seasonality, as part of their advertising campaigns, and other factors.



Average Monthly Revenue per Subscriber. We calculate our average monthly revenue per subscriber by dividing the revenue generated from
subscriptions in a period by the average number of subscribers in the period, divided again by the number of months in the period. Our average number of subscribers is calculated by taking the average of the beginning and ending number of
subscribers for the period. Our average monthly revenue per subscriber is a key indicator of our ability to monetize our marketplace, and we monitor changes in this metric to measure the effectiveness of our marketplace monetization strategy. In the
year ended December 31, 2012, our average monthly revenue per subscriber increased to $156 from $110 in the year ended December 31, 2011, a 42% increase. We have been able to increase our average monthly revenue per subscriber by launching
new products to sell to existing customers, raising prices in certain geographic markets, and selling to existing subscribers the additional advertising inventory created by traffic growth to our marketplace. In addition, in

geographic markets that show strong demand for our subscription products  those where inventory is sold out and wait lists to purchase our products existaverage monthly revenue per
subscriber is higher than in markets with less demand for our products. While the average monthly revenue per subscriber has increased and may continue to increase in absolute dollars period-over-period, the rate of increase has slowed and we expect
that the rate of increase may continue to slow as the average monthly revenue per subscriber increases. We believe that the slowing growth rate of our average monthly revenue per subscriber is the result of our larger subscriber base and the
resulting challenge associated with achieving higher growth rates. Despite this slowing growth rate, we believe we have significant opportunities to continue to increase average monthly revenue per subscriber by further penetrating markets and by
offering new products to existing subscribers.

Revenue

Our revenue is comprised of marketplace revenue and media revenue.

Marketplace Revenue. Marketplace revenue primarily consists of our fixed-fee subscription products. We currently provide two sets
of products to real estate professionals on a subscription basis. The first set of products, which include Trulia Local Ads and Trulia Mobile Ads, enables real estate professionals to promote themselves on our search results pages and
property details pages for a local market area. Real estate professionals purchase subscriptions to this product based upon their specified market share for a city or zip code, at a fixed monthly price, for periods ranging from one month to one
year, with pricing depending on the location and the percentage of market share purchased. We price Trulia Local Ads and Trulia Mobile Ads subscriptions similarly based on geography, the share of a market, and demand. Our second set of
products allows real estate professionals to receive prominent placement of their listings in our search results. Real estate professionals sign up for subscriptions to this service at a fixed monthly price for periods that generally range from
one month to 12 months. We recognize our subscription revenue ratably over the term of the subscription.

Media
Revenue. We derive media revenue from sales of display advertisements to real estate advertisers, such as home improvement companies and mortgage lenders. We also derive media revenue from sales of display advertisements to leading consumer
brands, such as home furnishings, cable, and automotive companies. Our media products enable our customers to display advertisements to promote their brand on our website and mobile website, m.trulia.com. Pricing is based on advertisement size and
position on our web page, and fees are billed monthly, based on a per impressions or a per click basis. Impressions are the number of times an advertisement is loaded on our web page, and prices are measured on a cost per thousand, or CPM, basis.
Clicks are the number of times users click on an advertisement, and prices are measured on a cost per click, or CPC, basis. CPC is based on the number of times a user clicks an advertisement. This media revenue is recognized in the periods the
clicks or impressions are delivered. Our media revenue is generated primarily through advertisements placed on our website, although we do generate some media revenue from display advertising on our mobile website. We price display advertisements on
our mobile products on a per-impression basis. We have also started running display advertising campaigns for advertisers on certain of our iPhone and iPad mobile

applications and we expect to offer display advertising on our other mobile applications in the future. As our mobile web pages and mobile applications offer less space on which to display
advertising, a shift in user traffic from our website to mobile products could decrease our advertising inventory and negatively affect our media revenue. We do not believe that we have experienced a shift in user traffic from our website to our
mobile applications, as our monthly unique visitors and mobile monthly unique visitors each continued to grow at a rapid pace.

During the years ended December 31, 2010, 2011, and 2012, we recognized marketplace revenue and media revenue as follows:

For the year ended December 31, 2010, because we had not yet
established the fair value for each element, revenue for multiple element arrangements was recognized ratably over the contract term for financial reporting purposes. However, in order to provide added transparency and help facilitate the discussion
herein, we have separated marketplace and media revenue based on selling prices, which management has determined to be a reasonable separation methodology.

Both our marketplace revenue and media revenue have grown over the periods disclosed above. Our marketplace revenue has grown significantly faster than our media revenue and, as a result, now constitutes
the majority of our total revenue. We expect this trend to continue and for the percentage of our media revenue, as a share of our total revenue, to continue to decline.

Technology and Development. Technology and development expenses consist primarily of headcount related expenses including salaries, bonuses, benefits and stock-based compensation expense,
third-party contractor fees, and allocated overhead primarily associated with developing new technologies. Technology and development also includes amortization expenses related to capitalized costs from internal and external development activities
for our marketplace. We expect our technology and development expenses to increase in absolute dollars as we continue to invest in the development of our products.

Sales and Marketing. Sales and marketing expenses consist primarily of headcount-related expenses including salaries, bonuses, commissions, benefits and stock-based compensation expense for sales,
customer service, marketing, and public relations employees and third-party contractor fees. Sales and marketing expenses also include other sales expenses related to promotional and marketing activities, and allocated overhead. We expect sales and
marketing expenses to increase in absolute dollars as we hire additional employees to expand our sales force and to support our direct marketing initiatives.

General and Administrative. General and administrative expenses consist primarily of headcount related expenses including salaries, bonuses, and benefits and stock-based compensation expense for
executive, finance, accounting, legal, human resources, recruiting, and administrative support personnel. General and administrative expenses also include legal, accounting, and other third-party professional service fees, bad debt, and allocated

overhead. We expect our general and administrative expenses to increase in absolute dollars as we expand our financial, accounting, and legal personnel and resources to support our public
reporting requirements.

Interest expense consists primarily of interest on our
outstanding long-term debt and capital lease obligations. See Note 6 of our audited financial statements included elsewhere in this prospectus for more information about our long-term debt and Note 7 for more information about our capital lease
obligations.

Change in Fair Value of Warrant Liability

Change in the fair value of the warrant liability includes charges from the remeasurement of our preferred stock warrant liability on a
mark-to-market basis as of each period end. These preferred stock warrants became warrants to purchase common stock upon the completion of our IPO, at which time the warrant liability was remeasured to fair value and the remaining liability was
reclassified to additional paid-in capital. See Note 9 of the audited financial statements included elsewhere in this prospectus for more information about our preferred stock warrants.

Provision for Income Taxes

Our provision for income taxes has not been historically significant to our business as we have incurred losses to date. We currently have federal and state net operating loss carryforwards of $43.4
million and $43.7 million, which expire at various dates beginning in 2025 and 2015, respectively. See Note 12 of our audited financial statements included elsewhere in this prospectus for more information about our provision for income taxes.

Revenue increased to $68.1 million in the year ended December 31, 2012 from $38.5 million in the year ended December 31, 2011, an increase of $29.6 million, or 77%. Marketplace revenue and media
revenue represented 67% and 33%, respectively, of total revenue in the year ended December 31, 2012, compared to 58% and 42%, respectively, of total revenue in the year ended December 31, 2011. The increase in total revenue was
attributable to the significant growth of our subscriber base, an increase in our unique monthly visitors, and increased prices. The increase in marketplace revenue as a percentage of total revenue was the result of significant growth in our
subscription business, driven by increases in total subscribers and average monthly revenue per subscriber, which outpaced the growth of our media business.

2010 Compared to 2011

Revenue increased to $38.5 million in the year ended
December 31, 2011 from $19.8 million in the year ended December 31, 2010, an increase of $18.7 million, or 95%. Marketplace revenue and media revenue represented 58% and 42%, respectively, of total revenue in the year ended
December 31, 2011, compared to 47% and 53%, respectively, of total revenue in the year ended December 31, 2010. The increase in marketplace revenue as a percentage of total revenue was the result of significant growth in our subscription
business, driven by increases in total subscribers and average monthly revenue per subscriber, which outpaced the growth of our advertising business.

During the years ended December 31, 2010, 2011, and 2012, we recognized marketplace
revenue and media revenue as follows:

herein, we have separated marketplace and media revenue based on selling prices, which management has determined to be a reasonable separation methodology.

2011 Compared to 2012

Marketplace revenue increased to $45.5 million in
the year ended December 31, 2012 from $22.3 million in the year ended December 31, 2011, an increase of $23.2 million, or 104%. This increase was primarily attributable to growth in the number of subscribers, price increases, and sales of
our mobile subscription product. The overall subscriber base grew by 45% to 24,443 subscribers as of the year ended December 31, 2012 from 16,849 subscribers as of the year ended December 31, 2011. In May 2012, we launched our most
significant mobile subscription product for agents, Trulia Mobile Ads, that resulted in an additional $4.4 million of marketplace revenue for the year ended December 31, 2012. Much of the 42% increase in average monthly revenue per
subscriber, from $110 in the year ended December 31, 2011 to $156 in the year ended December 31, 2012, was attributable to increased sales and higher pricing for our Trulia Local Ads product, as well as sales of our Truilia
Mobile Ads product.

Media revenue increased to $22.6 million in the year ended December 31, 2012 from $16.3 million
in the year ended December 31, 2011, an increase of $6.3 million, or 39%. This increase was primarily attributable to the strong year-over-year growth in our average monthly unique visitors from 14.8 million in the year ended
December 31, 2011, to 23.1 million in the year ended December 31, 2012, an increase of 57%. We also experienced a significant increase in display advertisement sales to home builders as a result of the improving real estate market.
Although there is a correlation between monthly unique visitors and our media revenue, it is not a direct correlation. The growth rate in our monthly unique visitors has outpaced the growth rate of our media revenue.

2010 Compared to 2011

Marketplace revenue increased to $22.3 million in the year ended December 31, 2011 from $9.4 million in the year ended December 31, 2010, an increase of $12.9 million, or 138%. This increase in
marketplace revenue was primarily attributable to the 67% increase in the number of total subscribers from 10,070 as of December 31, 2010 to 16,849 as of December 31, 2011. This increase in total subscribers resulted in a $5.8 million
increase in marketplace revenue during the year ended December 31, 2011 when compared to the year ended December 31, 2010. The increase in marketplace revenue was also partly attributable to a 38% increase in the average monthly revenue
per subscriber from $80 in the year ended December 31, 2010 to $110 in the year ended December 31, 2011. This increase in average revenue per subscriber resulted in a $4.9 million increase in marketplace revenue during the year ended
December 31, 2011 when compared to the year ended December 31, 2010.

Media revenue increased to $16.3 million in
the year ended December 31, 2011 from $10.4 million in the year ended December 31, 2010, an increase of $5.9 million, or 56%. This increase in media revenue was primarily the result of the increase in the number of impressions sold on a
CPM or CPC basis as we recognized

an increase in overall advertiser demand for our display advertising inventory during the year ended December 31, 2011. These increases were primarily driven by an increase in our average
monthly unique visitors from 7.9 million in the year ended December 31, 2010 to 14.8 million in the year ended December 31, 2011, an increase of 86%.

Cost of revenue increased to $10.0 million in the year ended December 31, 2012 from $5.8 million in the year ended December 31, 2011, an increase of $4.2 million, or 73%. This increase in cost
of revenue was primarily the result of a $1.9 million increase in headcount and related benefits due primarily to the growth in sales and expansion of the business overall, and a $1.5 million increase attributable to content license fees, hosting
fees, and credit card fees due to higher subscription revenue. Cost of revenue remained at 15% of revenue in the years ended December 31, 2011 and 2012.

2010 Compared to 2011

Cost of revenue increased to $5.8 million in
the year ended December 31, 2011 from $3.7 million in the year ended December 31, 2010, an increase of $2.1 million, or 58%. This increase in cost of revenue was primarily the result of a $0.8 million increase in headcount and
related benefits due to growth in customer service headcount following the establishment of our new facility in Denver in February 2011 and a $0.3 million increase in our credit card fees, a $0.2 million increase in content license fees, and a $0.4
million increase in hosting fees, due to growth in our subscriptions and additional traffic. Cost of revenue declined to 15% of revenue in the year ended December 31, 2011 from 18% of revenue in the year ended December 31, 2010.

Technology and development expenses increased to $20.2 million in the year ended December 31, 2012 from $14.7 million in the year ended December 31, 2011, an increase of $5.5 million, or 38%.
This increase was comprised primarily of a $4.1 million increase in headcount and related benefits, a $0.4 million increase in stock-based compensation expenses, a $0.4 million increase attributable to higher facilities related expenses in the
current year due to significant leasehold improvements completed in the year ended December 31, 2012 in our Denver facility, as well as an increase in capitalized product development costs. Technology and development expenses decreased to 30%
of revenue in the year ended December 31, 2012 from 38% of revenue in the year ended December 31, 2011, reflecting the increase in our revenue.

Technology and development expenses increased to $14.7 million in the year ended December 31, 2011 from $8.8 million in the year

increase in equipment and facilities related costs to support the headcount growth, a $0.6 million increase related to additional recruiting and travel expenses, and a $0.3 million increase related to amortization of capitalized product
development costs. Technology and development expenses declined to 38% of revenue in the year ended December 31, 2011 from 44% of revenue in the year ended December 31, 2010, reflecting the increase in our revenue.

Sales and marketing expenses increased to $33.7 million in the year ended December 31, 2012 from $17.7 million in the year ended December 31, 2011, an increase of $16.0 million, or 90%. This
increase was primarily the result of a $12.4 million increase in headcount and related benefits associated with the expansion of our sales personnel to support our revenue growth, a $0.2 million increase in stock-based compensation, and a $2.5
million increase in marketing and advertising expenses due to the increased marketing activities for Trulia Mobile Ads. These increases were partially offset by a $1.2 million decrease in external contractor fees as we decreased usage of
external contractors and hired more full-time employees. Sales and marketing expenses increased to 49% of revenue in the year ended December 31, 2012 from 46% of revenue in the year ended December 31, 2011, due to substantial headcount
growth in our sales and marketing function and marketing expense associated with the launch of our Trulia Mobile Ads product in May 2012.

2010 Compared to 2011

Sales and marketing expenses increased to $17.7
million in the year ended December 31, 2011 from $8.6 million in the year ended December 31, 2010, an increase of $9.1 million, or 105%. This increase was primarily the result of a $4.1 million increase in headcount and related benefits, a
$2.7 million increase in consulting costs largely for temporary contractors when we opened our new Denver facility, where we subsequently hired to expand our sales team, a $1.0 million increase in facilities related costs, a $0.5 million increase in
depreciation due to our growth, and a $0.4 million increase in marketing and advertising expenses. Sales and marketing expenses increased to 46% of revenue in the year ended December 31, 2011 from 44% of revenue in the year ended
December 31, 2010.

General and administrative expenses increased to $13.7 million in the year ended December 31, 2012 from $6.1 million in the year
ended December 31, 2011, an increase of $7.5 million, or 123%. This increase was primarily the result of a $2.9 million increase in headcount and related benefits, a $0.4 million increase in stock-based compensation expenses, a $0.3 million
increase in facilities related expenses due to headcount growth, and a $2.5 million increase in the outside accounting services related to our IPO in September 2012. General and administrative expenses increased to 20% of revenue in the year ended
December 31, 2012 from 16% of revenue in the year ended December 31, 2011 primarily due to the significant increase in our financial, accounting, and legal headcount and increased expenses for third-party service providers to support our
transition to being a public reporting company.

2010 Compared to 2011

General and administrative expenses increased to $6.1 million in the year ended December 31, 2011 from $2.5 million in the year ended
December 31, 2010, an increase of $3.6 million, or 145%. This increase was primarily the result of a $1.5 million increase in headcount and related benefits, a $0.8 million increase in professional services related to legal, recruiting, and
accounting as we scaled our business, and a $0.7 million increase in stock-based compensation expenses. General and administrative expenses increased to 16% of revenue in the year ended December 31, 2011 from 13% in the year ended
December 31, 2010.

Interest expense increased to $1.0 million in the year ended December 31, 2012 from $0.4 million in the year ended December 31, 2011, an increase of $0.6 million, or 161%. The increase was
attributable to an incremental interest expense associated with our outstanding indebtedness, and the remaining increase was attributable to revaluation of the preferred stock warrant liability throughout the year.

2010 Compared to 2011

Interest expense increased to $0.4 million in the year ended December 31, 2011 from $39,000 in the year ended December 31, 2010. This increase was primarily the result of the incremental
interest expense associated with the increased principal amount of our outstanding indebtedness, which increased from $2.0 million as of December 31, 2010 to $9.6 million as of December 31, 2011.

Change in fair value of warrant liability increased to ($368,766) in the year ended December 31, 2012 from ($15,938) in the year
ended December 31, 2011, an increase of $ 352,828, or 2,206%. This increase was attributable to an increase in the fair value of the warrant to purchase convertible preferred stock. We issued this warrant when a new credit facility was
established in September 2011. Upon the first public filing of our registration statement in August 2012, the anti-dilution provisions in this warrant terminated. As a result, the preferred stock warrant liability was remeasured to fair value and
the remaining liability was reclassified to additional paid-in capital. Immediately prior to completion of our IPO in September 2012, the preferred stock converted to common stock and this warrant to purchase preferred stock converted into a warrant
to purchase common stock. Because this warrant no longer contains anti-dilution provisions, this warrant will no longer be remeasured to fair value on an ongoing basis.

Quarterly Trends

Revenue and gross profit increased sequentially in all quarters presented. The strong increase in consumer adoption of our
website and mobile applications was reflected in the significant growth in users over the periods, which contributed to substantial increases in marketplace and media revenue. Although we experienced sequential increases in media revenue during each
of the four quarters ended December 31, 2011, the growth in media revenue slowed during the year ended December 31, 2011 and media revenue decreased in the three months ended March 31, 2012. The primary reason for the decrease in
media revenue during the three months ended March 31, 2012 was the loss of a significant customer which declared bankruptcy. Since that time, we have generated sequential increases in media revenue each quarter. Although the growth rate of
media revenue has slowed, we expect media revenue to grow as our business grows but at a slower rate than our marketplace

revenue. Accordingly, we also recognized a shift toward a greater percentage of our total revenue resulting from marketplace products as opposed to media products. The growth in our subscription
business continues to outpace the growth in our advertising business and we expect this trend to continue. We have also experienced seasonality in our revenue in the past as a result of lower traffic in the fourth calendar quarter due to the
traditionally lower volume of home sale transactions during the holiday season. In addition, our operating expenses have increased sequentially as a result of our growth, primarily related to increased headcount to support our expanded operations.

Adjusted EBITDA

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated below. See the section titled Selected Financial
and Other Data for the detailed reconciliation to our net loss and for more information on our use and the limitations of Adjusted EBITDA as a measure of our financial performance.

Liquidity and Capital Resources

As of December 31, 2012, our principal sources of liquidity were cash and cash equivalents totaling $100.0 million which consists of bank deposits and money market funds. On September 25, 2012,
we completed our IPO pursuant to which we sold 5,900,000 shares of our common stock, which includes 900,000 shares sold pursuant to the exercise by the underwriters of an option to purchase additional shares, at a public offering price of $17.00 per
share, resulting in net proceeds to us of $89.4 million, after deducting underwriting discounts and commissions and offering expenses payable by us. In addition, another 1,000,000 shares were sold by certain selling stockholders. We did not receive
any proceeds from sales by the selling stockholders. Prior to the IPO, our operations were financed primarily by the net proceeds of $32.6 million from the sales of shares of our convertible preferred stock and $15.2 million in proceeds from the
issuance of indebtedness. As of December 31, 2012, we had $9.8 million of outstanding debt from a credit facility, which reflects a debt discount of $241,000.

We have incurred cumulative losses of $47.1 million from our operations to date, and expect to incur additional losses in the future. We believe that our cash balances and the cash flows generated by
operations will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditures for at for the next 12 months. However, our future capital requirements will depend on many factors, including our rate of revenue
growth, the cash that may be used in connection with acquisitions or other investments, the expansion of our sales and marketing activities, and the timing and extent of our spending to support our technology and development efforts. To the extent
that existing cash and cash equivalents, and cash from operations are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. Additional funds may not be available on
terms favorable to us or at all.

In September 2011, we entered into a loan and security agreement with Hercules Technology Growth Capital, Inc., or Hercules, providing for
a secured term loan facility, or the credit facility, in an aggregate principal amount of up to $20.0 million to be used for general business purposes. Indebtedness we incur under this agreement is secured by substantially all of our assets. This
agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer
assets, merge or consolidate, and make acquisitions. As of December 31, 2012, we had drawn $10.0 million in term loans under the credit facility. Our ability to draw additional funds under the credit facility expired on December 31, 2012.

Cash Flows from Operating Activities

Cash provided by operating activities for the year ended December 31, 2012 was $4.2 million. The primary component of our cash flows
during the year ended December 31, 2012 was our net loss of $10.9 million. The cash flows from our net loss were more than offset by our non-cash operating activities and net cash flows provided through changes in certain of our operating
assets and liabilities. Specifically, we recognized non-cash charges of $3.6 million for depreciation and amortization of our property and equipment, $2.6 million for stock-based compensation, and $0.4 million for the fair value remeasurement of the
preferred stock warrant liability. We also recognized changes in operating assets and liabilities which provided $8.3 million of cash from operating activities. Of this $8.3 million, $1.0 million related to an accrued withholding tax from stock
option exercises collected from a former employee, which we remitted to the appropriate tax authorities after December 31, 2012. The primary driver of the changes in our operating assets and liabilities was an $8.5 million increase in deferred
revenue due to the increase in the number of total subscribers and average monthly revenue per subscriber during the year. Changes in our operating assets and liabilities were also affected by an increase in accrued liabilities in the amount of $1.8
million, due primarily to the overall growth in our business during the year; increases in accrued compensation and benefits of $2.5 million due to the growth in our headcount, an increase in accounts receivable of $2.5 million, primarily due to our
revenue growth but also to timing of collections; and increases in prepaid expenses and other current assets of $0.9 million mainly due to expansion of our facilities in Denver and overall growth in our business.

Cash provided by operating activities for the year ended December 31, 2011 was $1.1 million. The primary component of our cash flows
during the year ended December 31, 2011 was our net loss of $6.2 million. The cash flows from our net loss were more than offset by our non-cash operating activities and net cash flows provided through changes in certain of our operating assets
and liabilities. Specifically, we recognized non-cash charges of $2.5 million for depreciation and amortization of our property and equipment, $1.5 million for stock-based compensation, and $0.2 million provision for doubtful accounts. We also
recognized changes in operating assets and liabilities which provided $3.0 million of cash from operating activities. The primary driver of the changes in our operating assets and liabilities was a $3.0 million increase in deferred revenue due to
the increase in the number of total subscribers and average monthly revenue per subscriber during the year. Changes in our operating assets and liabilities were also significantly affected by an increase in accounts receivable of $1.4 million,
primarily due to our revenue growth but also to timing of certain payments related to generally

slower collections during the year. Changes in our operating assets and liabilities were also affected by increases in accrued compensation and benefits of $0.7 million and deferred rent of $0.7
million due to the growth in our headcount and expanded facilities during the year. Changes in our operating assets and liabilities were also affected by an increase in accounts payable and accrued liabilities in the amount of $0.4 million, due
primarily to the overall growth in our business during the year.

Cash used in operating activities for the year ended
December 31, 2010 was $1.1 million. The primary component of our cash flows during the year ended December 31, 2010 was our net loss of $3.8 million. The cash flows from our net loss were partially offset by our non-cash operating
activities and net cash flows provided through changes in certain of our operating assets and liabilities. Specifically, we recognized non-cash charges of $1.0 million for depreciation and amortization of our property and equipment, $0.4 million for
stock-based compensation, and $0.1 million for provision for doubtful accounts. We also recognized changes in operating assets and liabilities which provided $1.3 million of cash from operating activities. The primary driver of the changes in our
operating assets and liabilities was a $1.3 million increase in deferred revenue due to the increase the number of total subscribers and average monthly revenue per subscriber during the year. Changes in our operating assets and liabilities were
also significantly affected by increases in accrued compensation and benefits in the amount of $0.7 million and accounts receivable of $0.7 million due primarily to our growth in headcount and revenue, respectively, during the year. Changes in our
operating assets and liabilities were also affected by an increase in deferred rent of $0.4 million due primarily to the growth of our business during the year and by an increase in accounts payable and accrued liabilities of $0.3 million.

Cash Flows from Investing Activities

Cash used in investing activities for the year ended December 31, 2012 was primarily related to the acquisition of property and equipment in the amount of $5.5 million, which was partially offset by
the maturity of short-term investments in the amount of $4.3 million.

Historically, cash used in investing activities was
primarily related to the acquisition of property and equipment and patents, which amounted to $4.8 million and $2.6 million for the years ended December 31, 2011 and 2010. Cash used in investing activities was also attributable to the increases
in our restricted cash and deposit balance of $2.2 million and $2.1 million in the years ended December 31, 2011 and 2010.

Cash Flows from Financing Activities

Cash flows from financing activities for the year ended December 31, 2012 of $90.8 million was comprised of net proceeds of $89.4 million from our IPO in September 2012 and proceeds of $1.7 million
from the exercise of stock options, partially offset by $0.3 million of capital lease payments.

Cash provided by financing
activities for the year ended December 31, 2011 of $8.2 million was primarily comprised of proceeds of $12.0 million from additional borrowings and $0.4 million from exercise of stock options, which were partially offset by $4.2 million of
capital lease and long-term debt repayments.

Cash provided by financing activities for the year ended December 31, 2010
of $1.4 million was primarily comprised of proceeds of $2.1 million from additional borrowings which were partially offset by $0.8 million of capital lease and long-term debt repayments.

The Credit Facility carries an interest rate equal to the greater of the
prime rate plus 2.75% or 6% for the first tranche, and a rate equal to the greater of the prime rate plus 5.5% or 8.75% for the second and third tranches.

We had unrecognized tax benefits in the amount of $20,000 as of December 31, 2012 related to uncertain tax positions. However, there
is uncertainty regarding when these liabilities will require settlement so these amounts were not included in the contractual obligations table above.

Off-Balance Sheet Arrangements

We have not entered into any off-balance
sheet arrangements and do not have any holdings in variable interest entities.

Segment Information

We have one business activity and operate in one reportable segment.

Quantitative and Qualitative Disclosures about Market Risk

We are exposed
to certain market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities as follows:

Interest Rate Risk

We had cash and cash equivalents of
$100.0 million as of December 31, 2012, which consists of bank deposits and money market funds. Such interest-earning instruments carry a degree of interest rate risk. To date, fluctuations in interest income have not been significant. We
also had total outstanding debt of $9.8 million as of December 31, 2012, of which $2.7 million is due within 12 months. Amounts outstanding under our credit facility carry variable interest rates ranging from 6.0% to 8.75%.

The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing
risk. We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure. Due to the short-term nature of our investments, we have not been exposed
to, nor do we anticipate being exposed to, material risks due to changes in interest rates. The interest rate on our outstanding debt is variable. A hypothetical 10% change in interest rates during any of the periods presented would not have had a
material impact on our financial statements.

Our financial statements are prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The
preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We base our estimates on historical experience and
on various other assumptions that we believe to be reasonable. In many instances, we could have reasonably used different accounting estimates, and in other instances changes in the accounting estimates are reasonably likely to occur from
period-to-period. Actual results could differ significantly from our estimates. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results
of operations and cash flows will be affected. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving our
judgments and estimates.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price to the buyer is fixed or
determinable, and collection is reasonably assured. We consider a signed agreement, a binding insertion order, or other similar documentation reflecting the terms and conditions under which products will be provided to be persuasive evidence of an
arrangement. Collectability is assessed based on a number of factors, including payment history and the creditworthiness of a customer. If it is determined that collection is not reasonably assured, revenue is not recognized until collection becomes
reasonably assured, which is generally upon receipt of cash.

Our revenue includes marketplace revenue and media revenue.
Marketplace revenue consists primarily of subscription revenue, which is recognized ratably over the term of the subscription. Media revenue consists primarily of advertisement sales, which is recognized in the periods the clicks or impressions are
delivered.

We also enter into arrangements with customers that include combinations of cost per thousand impressions, or CPM,
media placement, cost per click, or CPC, media placements, and subscription products. Beginning on January 1, 2011, we adopted new authoritative guidance on multiple-element arrangements, using the prospective method for all arrangements
entered into or materially modified from the date of adoption. Under this new guidance, we allocate arrangement consideration in multiple-element revenue arrangements at the inception of an arrangement to all deliverables or those packages in which
all components of the package are delivered at the same time, based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor-specific objective evidence, or VSOE, if available;
(ii) third-party evidence, or TPE, if VSOE is not available, and (iii) best estimate of selling price, or BESP, if neither VSOE nor TPE is available.

VSOE- We determine VSOE based on our historical pricing and discounting practices for the specific product when sold separately. In determining VSOE, we require that a substantial
majority of the standalone selling prices for these products fall within a reasonably narrow pricing range. For certain subscription products, we have been able to establish VSOE.

TPE- When VSOE cannot be established for deliverables in multiple-element arrangements, we apply judgment with respect to
whether we can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our go-to-market strategy differs from that of our peers and our offerings contain a
significant level of differentiation such that the comparable pricing of our products cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor selling prices are on a standalone basis. As a result, we have not
been able to establish selling price based on TPE.

BESP- When we are unable to establish selling price
using VSOE or TPE, we use BESP in the allocation of arrangement consideration. The objective of BESP is to determine the price which we would transact a sale

if the service were sold regularly on a standalone basis. As we have not been able to establish VSOE or TPE for CPM media placements, CPC media placements, and certain subscription products, we
determine BESP for these deliverables based on the following:



The list price represents a component of our go-to-market strategy established by senior management. Our list prices are based on the features of the
products offered. These features, which consist of the size and placement of the advertisements on our website, impact the list prices which vary depending on the specifications of the features. In addition, the list prices are impacted by market
conditions, including the conditions of the real estate market and economy in general, and our competitive landscape; and



Analysis of our selling prices for these deliverables.

We limit the amount of allocable arrangement consideration to amounts that are fixed or determinable and that are not contingent on future performance or future deliverables. We regularly review BESP.
Changes in assumptions or judgments or changes to the elements in the arrangement could cause a material increase or decrease in the amount of revenue that we report in a particular period.

Allowances for Doubtful Accounts

We record a provision for doubtful accounts based on historical experience and a detailed assessment of the collectability of our accounts receivable. To assist with the estimate, our management considers
certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances, and current economic conditions that may affect a customers ability to pay. In cases where we become aware of circumstances that
may impair a specific customers ability to meet its financial obligations, we record a specific allowance against amounts due from the customer and thereby reduce the net recognized receivable to the amount we reasonably believe will be
collected. There is significant judgment involved in estimating the allowance for doubtful accounts.

Goodwill

Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible assets
acquired. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. We have determined that we operate as one reporting unit and
have selected December 1 as the date to perform our annual impairment test. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. If the net book value exceeds
its fair value, then we would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. When performing the valuation of our goodwill, we make assumptions regarding our estimated future cash flows to
determine the fair value of our business. If our estimates or related assumptions change in the future, we may be required to record impairment loss related to our goodwill. We have not recognized any goodwill impairments since our inception.

Impairment of Long-Lived Assets

We assess the impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and
used is measured first by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, an impairment loss would be recognized. When
measuring the recoverability of these assets, we will make assumptions regarding our estimated future cash flows expected to be generated by the assets. If our estimates or related assumptions change in the future, we may be required to impair these
assets. We have not recognized any impairment of long-lived assets to date.

Costs incurred in connection with the development of our marketplace are accounted for as follows: all costs incurred in the preliminary
project and post-implementation stages are expensed as incurred. Certain costs incurred in the application development stage of a new product or projects to provide significant additional functionality to existing products are capitalized if certain
criteria are met. Maintenance and enhancement costs are typically expensed as incurred. Such costs are amortized on a straight-line basis over the estimated useful lives of the related assets, which was estimated to be two years. Amortization
expense is included in technology and development expense in the statements of operations.

Stock-Based Compensation

We recognize compensation costs related to stock-based awards granted to employees based on the estimated fair value
of the awards on the date of grant, net of estimated forfeitures. For the stock options, we estimate the grant date fair value, and the resulting stock-based compensation expense using the Black-Scholes option-pricing model. For the restricted stock
units, the grant date fair value equals the market value of the underlying stock on the date of grant. The grant date fair value of the stock-based awards is recognized on a straight-line basis over the requisite service period, which is the vesting
period of the respective awards.

The fair value of the awards granted during the years ended December 31, 2010, 2011 and
2012 was calculated using the Black-Scholes option-pricing model with the following weighted average assumptions:

Year Ended December 31,

Risk-free interest rate

Dividend rate

0%

The Black-Scholes option-pricing model requires the use of highly subjective and complex
assumptions, including the expected term and the price volatility of the underlying stock, which determine the fair value of stock-based awards. These assumptions include:



Expected term. The expected term represents the period that the stock-based awards are expected to be outstanding. We estimate the expected term
of the options based on a study of publicly traded industry peer companies and the historical data on employee exercises and post-vesting employment termination behavior taking into account the contractual life of the stock-based awards;



Expected volatility. The expected volatility is derived from the historical stock volatilities of several comparable publicly listed peers over
a period approximately equal to the expected term of the stock-based awards. We use this method because we have limited information on the volatility of our common stock because of our short trading history. When making the selections of our
comparable industry peers to be used in the volatility calculation, we considered the size, operational and economic similarities to our principle business operations;



Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon
U.S. Treasury notes with maturities approximately equal the expected term of the stock-based awards; and



Expected dividend. The expected dividend is assumed to be zero as we have never paid dividends and have no current plans to pay any dividends on
our common stock.

In addition to the assumptions used in the Black-Scholes option-pricing model, we must
also estimate a forfeiture rate to calculate the stock-based compensation for our awards. Our forfeiture rate is based on an

analysis of our actual forfeitures. We will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover, and other
factors. Quarterly changes in the estimated forfeiture rate can have a significant impact on our stock-based compensation expense as the cumulative effect of adjusting the rate is recognized in the period the forfeiture estimate is changed. If a
revised forfeiture rate is higher than the previously estimated forfeiture rate, an adjustment is made that will result in a decrease to the stock-based compensation expense recognized in our financial statements. If a revised forfeiture rate is
lower than the previously estimated forfeiture rate, an adjustment is made that will result in an increase to the stock-based compensation expense recognized in our financial statements.

We will continue to use judgment in evaluating the expected volatility, expected terms, and forfeiture rates utilized for our stock-based
compensation calculations on a prospective basis. As we continue to accumulate additional data related to our common stock, we may have refinements to the estimates of our expected volatility, expected terms, and forfeiture rates, which could
materially impact our future stock-based compensation expense.

Stock-Based Awards Granted Prior to our Initial Public
Offering

Prior to our IPO, we also estimated the fair value of the common stock underlying our stock-based awards when
performing the fair value calculations with the Black-Scholes option-pricing model. The fair value of the common stock underlying our stock-based awards was estimated on each grant date by our board of directors, with input from management. Our
board of directors is comprised of employee and non-employee directors with significant experience investing in and operating companies in the real estate and technology industries. As such, we believe that our board of directors has the relevant
experience and expertise to determine a fair value of our common stock on each respective grant date. Given the absence of a public trading market of our common stock prior to our IPO, and in accordance with the American Institute of Certified
Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation, our board of directors exercised reasonable judgment and considered numerous objective and subjective factors to determine the
fair value of our common stock including:



contemporaneous valuations performed by unrelated third party specialists;



rights, preferences, and privileges of our convertible preferred stock relative to those of our common stock;



actual operating and financial performance;



present value of future cash flows;



likelihood of achieving a liquidity event, such as an IPO or a sale of our company given prevailing market conditions and the nature and history of our
business;



illiquidity of stock-based awards involving securities in a private company;



experience of our management team;



market multiples of comparable companies in our industry;



stage of development;



industry information such as market size and growth; and



macroeconomic conditions.

The independent valuations performed by unrelated third-party specialists were just one factor used by our board of directors to assist with the valuation of the common stock and our management and board
of directors have assumed full responsibility for the estimates. Our board of directors generally utilized the fair values of the common stock derived in the third-party valuations in determining the exercise price for options granted.

In valuing our common stock, our board of directors considered two valuation approaches to
determine the equity value of our business, an income approach and a market approach.

The income approach estimates the fair
value of a company based on the present value of the companys future estimated cash flows and the residual value of the company beyond the forecast period. These future values are discounted to their present values to reflect the risks
inherent in the company achieving these estimated cash flows. The discount rates are used in the income approach for early stage companies because these companies tend to be relatively risky investments and therefore command rates of return
commensurate with such risk. The discount rates used in our valuation were based primarily on benchmark venture capital studies of discount rates for other companies in our stage of development, considered along with industry based weighted average
cost of capital rates. Other significant inputs of the income approach (in addition to our estimated future cash flows themselves) include but are not limited to the long-term growth rate assumed in the residual value and normalized long-term
operating margin. The market approach estimates the fair value of a company by applying market multiples of comparable publicly traded companies in the same industry or similar lines of business. More specifically, we selected our comparable
publicly traded companies by analyzing various factors, including, but not limited to, industry similarity, financial risk, company size, geographic diversification, profitability, the availability of adequate financial data, and whether or not they
had an actively traded stock price. The market multiples are based on key metrics implied by the enterprise or acquisition values of comparable publicly traded companies and, for our valuations in 2012, we primarily utilized the last twelve months
and projected twelve months revenue multiples from our comparable publicly traded peers in the market approach. These observed multiples were averaged and then applied to our historical twelve months and projected revenue to arrive at an indication
of value. We deemed multiples of revenue to be the most relevant in our industry as we are still in a relatively high growth phase, and thus have not reached normalized profitability or generated positive historical profit thus making the
application of profit based multiples not possible or less reliable. Other significant inputs of the market approach include historical and projected operating metrics.

The enterprise value determined by the income and market approach was then allocated to the common stock using the option pricing method. The option pricing method, or OPM, treats common stock and
convertible preferred stock as call options on a business, with exercise prices based on the liquidation preference of the convertible preferred stock. Therefore, the common stock has value only if the funds available for distribution to the
stockholders exceed the value of the liquidation preference at the time of a liquidity event such as a merger, sale or IPO, assuming the business has funds available to make a liquidation preference meaningful and collectible by the stockholders.
The common stock is modeled to be a call option with a claim on the business at an exercise price equal to the remaining value immediately after the convertible preferred stock is liquidated. The OPM uses the Black-Scholes option-pricing model to
price the call option. The OPM is appropriate to use when the range of possible future outcomes is so difficult to predict that forecasts would be highly speculative. The probability weighted expected return method, or PWERM, was considered but not
used due to the uncertainty of our estimates of the probabilities for future potential liquidity events.

Stock-Based
Awards Granted Subsequent to our Initial Public Offering.

For stock-based awards granted subsequent to our IPO, our board
of directors determined the fair market value based on the closing price of our common stock as reported on the New York Stock Exchange on the date of grant.

Stock-based compensation expense included in operating results during the years ended December 31, 2010, 2011 and 2012 was included
in cost and expenses as follows:

As of December 31, 2012, we had $7.0 million of unrecognized stock-based compensation expense for
stock options, net of estimated forfeitures, that is expected to be recognized over a weighted average period of 2.68 years. As of December 31, 2012, we had $520,000 of unrecognized stock-based compensation expense for restricted stock units,
net of estimated forfeitures, that is expected to be recognized over a weighted average period of 3.81 years. In future periods, our stock-based compensation expense is expected to increase as a result of our existing, unrecognized stock-based
compensation, to be recognized as these awards vest and as we issue additional stock-based awards to attract and retain employees.

Income Taxes

We account for our income taxes in accordance with the
asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for
operating losses and tax credit carryforwards. Management must make assumptions, judgments, and estimates to determine our current provision for income taxes and also our deferred tax assets and liabilities as well as any valuation allowance to be
recorded against a deferred tax asset.

Our assumptions, judgments, and estimates relative to the current provision for income
taxes take into account current tax laws, our interpretation of current tax laws, and possible outcomes of current and future audits conducted by domestic tax authorities. We have established reserves for income taxes to address potential exposures
involving tax positions that could be challenged by tax authorities. Although we believe our assumptions, judgments, and estimates are reasonable, changes in tax laws or our interpretation of tax laws, and the resolution of potential tax audits
could significantly impact the amounts provided for income taxes in our financial statements.

Our assumptions, judgments, and
estimates relative to the value of a deferred tax asset take into account predictions of the amount and category of future taxable income, such as income from operations or capital gains income. Actual operating results and the underlying amount and
category of income in future years could render our current assumptions, judgments and, estimates of recoverable net deferred taxes inaccurate. Any of the assumptions, judgments, and estimates mentioned above could cause our actual income tax
obligations to differ from our estimates, thus materially impacting our financial position and results of operations.

Since
inception, we have incurred operating losses, and accordingly, we have not recorded significant provisions for income taxes for any of the periods presented. We do not expect any significant changes until we are no longer incurring losses.

We have provided a full valuation allowance for net operating losses, credits, and other deferred tax assets for federal and
state income tax purposes. A valuation allowance is provided when based upon the available

evidence management concludes that it is more likely than not that some portion of the deferred tax assets will not be realized. We maintained a full valuation allowance as of December 31,
2012 due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets. As of December 31, 2012, we had federal and state net operating loss carry forwards of $43.4 million and $43.7
million. The federal net operating loss carry forward will expire at various dates beginning in 2025, if not utilized. If not used, the state net operating loss carry forward will expire at various dates beginning in the 2015.

Recently Issued and Adopted Accounting Pronouncements

Under the Jumpstart Our Business Startups Act, or JOBS Act, we meet the definition of an emerging growth company. We have
irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards,
orIFRS. This pronouncement was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. ASU 2011-04 changes certain fair
value measurement principles and enhances the disclosure requirements particularly for Level III fair value measurements. This pronouncement is effective for reporting periods beginning on or after December 15, 2011, with early adoption
prohibited. The adoption of this guidance did not have any impact on our results of operations or financial position.

In June
2011, the FASB issued ASU No. 2011-05, Presentation of ComprehensiveIncome, which requires an entity to present total comprehensive income, the components of net income, and the components of other comprehensive income
either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders
equity.
